Envisage Computer Modelling and Statistics for Agriculture Planning of ecological agricultural tourist attractions based on the concept of circular economy

With the continuous development of society and the continuous improvement of people ’ s living standards, leisure agricultural tourism based on agricultural production has gradually become popular, which takes agricultural landscape, agricultural experience and agricultural product shopping as content, and leisure agricultural tourist attractions have emerged. At present, some ecological agriculture projects are reconstruction or transformation projects, which are the recreational transformation of the original base for traditional agricultural projects in order to survive and seek market stimulation. However, due to the unscienti ﬁ c planning of the basic system, the low level of operation and management, and the lack of a scienti ﬁ c theoretical system for demonstration during the transformation process, the planning and transformation of the ecological agriculture project have not been promoted, and the project industry development has not been improved. Therefore, under the support of the concept of circular economy, this paper combines the Internet of Things technology to carry out the planning and analysis of ecological agricultural tourist attractions, and combines the experiments to analyse the e ﬀ ectiveness of this method. From the research point of view, it can be known that the ecological agricultural scenic area planning method constructed in this paper has certain e ﬀ ects.


Introduction
With the increasing development and improvement of information technology, the Internet of Things technology has been scientifically and rationally applied to the agricultural ecological tourism industry to realise the monitoring and integrated management of the backup links of tourism activities.Moreover, an integrated Internet of Things tourism platform has been built to provide tourists with information services, itinerary services, transportation services, commercial services, etc.At the same time, it promotes the intelligentisation and lowcarbonisation of eco-tourism, and improves the efficiency and level of eco-tourism management (Choo and Park 2018).In order to change the many problems faced by agricultural eco-tourism, it is necessary to innovate the traditional tourism model, increase the penetration rate of Internet of Things technology, and play an important role in tourism management and tourism services, and tourism environmental protection (Lee and Kwon 2017).
Eco-agricultural tourism is a type of tourism under the background of rural ecological environment.Moreover, it uses ecological agriculture and rural characteristic culture as its resources, applies aesthetics, ecology, economics principles, and sustainable development theories, uses human resources and natural resources to develop eco-agricultural tourism, and plans and constructs the rural environment in accordance with tourism environmental standards.At the same time, it takes eco-tourism as the main body, integrating agricultural production, the application of new agricultural technology, and tourist participation in sightseeing.In addition, it promotes the construction of ecological agriculture, the scientific and technological operation of agriculture, the exhibition of agronomic products, the promotion of agricultural and sideline products, and the good development of the rural ecological environment, so that tourists can feel agricultural modernisation and rural ecologicalisation (Flachs and Richards 2018).Eco-agricultural tourism is based on the rural ecological environment, farmland work, pastoral style, ecological agricultural production content and rural humanities.The importance of modernisation is the achievements in the field of science and knowledge, faster growth of mechanisation and growth, the explanation of social life, the appearance of balanced outlook in every walk of life.Through overall planning, layout, process design and a series of supporting facilities and services, it provides people with sightseeing, travel, and recuperation services.In addition, through tourist experience and participation in rural characteristic folk life, seasonal fruit and vegetable field visits and picking, and viewing of characteristic flowers and plants under intelligent technology, it combines fun and education to help people understand modern agriculture and increase agricultural knowledge.Eco-agricultural tourism is committed to integrating the economic functions of eco-agricultural production with the socio-economic functions of eco-tourism, and strengthening the economic functions of eco-agriculture, so as to achieve the goal of protecting the environment and promoting ecological sustainable development.At the same time, it combines ecological agriculture and ecological tourism to promote economic growth, social progress, and ecological stability.
The development of eco-agricultural tourism mainly relies on local eco-agricultural tourism resources.Among them, natural resources and human resources reflect the local natural scenery and cultural customs, which are extremely attractive to tourists.As an attractive condition for eco-agricultural tourism, these tourism resources can be used to develop eco-tourism, and these resources have the characteristics of recycling or renewable.In addition, eco-agricultural tourism is developed based on tourists' 'clothing, food, housing, and transportation', and consumes relatively few natural resources.The eco-agriculture is a number of associated systems of connected system of farming practice which are preserving or educating the status of efficiency of soil, organisation at the same period reducing damaging ecological effects.Ecological farming provides healthy agriculture and nutritious eating for yesterday and today by safeguarding soil, moisture, and weather, trying to promote bio-diversity, and attempting to avoid the use of chemical inputs or genetic modification.Recycling is an integral part of a circular economy, but should be regarded only as there are no other choices for re-use, re-manufacture, or fix.This really is the fundamental principle of the waste management hierarchy, that takes precedence most efficient waste management solutions.The main input is human resources, and the human resources provided to tourists have the characteristics of recycling and conform to the concept of sustainable development.Therefore, the development of eco-agricultural tourism is consistent with the green development concept of sustainable development currently required by our country.Eco-agricultural tourism also conforms to the characteristics of low energy consumption, low emission, resource saving, and sustainable development, and fully embodies the green development concept of sustainable development.

Eco-agricultural tourism started early in some developed countries and has become an important part of the tourism industry in many countries.Its eco-agricultural tourism revenue accounts for more than 20% of the overall tourism revenue (Park and Oh 2018).Eco-agricultural tourism mainly focuses on two development methods abroad (Alphey and Bonsall 2018).A type of vacation that focuses on leisure viewing functions and belongs to the viewing type.This type of eco-agricultural tourism is more popular in Central and Eastern European countries, mainly including Hungary, Finland and other places.Another way of eco-agricultural tourism is personal contact with farmland, which is participatory vacation.In this mode, tourists want to experience farming by themselves, pick food by themselves, experience the fun of the countryside during busy farming, and watch the countryside scenery.It is mainly popular in Japan, the United States and other places.Ecological farming is the most respectful of wildlife, as it produces lower pollution of aerosols, it produces less carbon dioxide, it prevents the greenhouse effect, it doesn't generate polluting waste and helps make energy savings since in the crop cultivation and in the production of the products it takes advantage.Tourists who choose eco-agricultural tourism are mostly people in the city who have received higher education and have certain economic conditions.Through eco-agricultural tourism, they release their work pressure in the beautiful countryside, invest in the slow-paced rural pastoral life from the high-pressure working environment, and look for the natural cultural atmosphere brought by nature (Marcis et al. 2019).Up to now, many foreign countries have used their own scientific and technological advantages to introduce intelligence and technology into eco-agricultural tourism to pursue high-tech and high value-added goals, and to build a modern agricultural science and technology park as a carrier to maximise agricultural productivity (Mueller et al. 2017).Some regions are committed to comprehensive development and utilisation of limited land, creating multi-functional high-tech agricultural parks such as ornamental leisure and foreign exchange earnings.At the same time, Singapore's agricultural park actively invests in infrastructure to increase the entertainment of the park.Moreover, it has carefully distributed the corridor into a characteristic agricultural ecological corridor with tourism characteristics and can provide fresh agricultural products to form a multi-

R E T R A C
T E D functional ecological agricultural system (Turner et al. 2019).In some countries, agricultural science and technology parks use a well-established team of experts and a large number of science and technology practitioners to manage (Adama et al. 2018).The nature of the farms in each garden in the agricultural sightseeing garden system designed by Duan et al. (2019) Corder Jessica and Irlbeck Erica (2018) proposed to apply the idea of closed loop to the whole process of product production.Cleaner production and wholeprocess control management models are more fundamentally effective than 'end management'.Therefore, it has received general attention and attention, and the implementation of circular economy has begun to transform from waste disposal to waste recycling.Ebert et al. (2019) believed that the primary goal of the development of circular economy is to establish resource management rules, so that the economic system where humans live and the natural system coexist harmoniously and sustainably develop.Alola Andrew Adewale and Uzuner Gizem (2020) reinterpreted the concept of circular economy from the perspective of resource scarcity.Moreover, it believes that there is a perfect and highly efficient material and energy cycle in nature, and the collection, transmission and decomposition of materials and energy in different ecosystems are realised through solar energy.The circular economy offers us with techniques we have to address respectively global warming and species extinction all while going to meet important social needs.It enables us to boost wealth, employment, and adaptability while reducing carbon emissions, disposal, and air quality.The idea of circular economy is to use nature as a prototype to artificially design material and energy cycles.Therefore, the development of circular economy is necessary and feasible for achieving sustainable development.
Roberts Richie and Robinson J. Shane (2018) built a wireless local area network to monitor crop growth and remote control of farmland and greenhouse.Zamani Naser and Mohammadi Maryam ( 2018) developed an approximately distributed wireless data acquisition and control system for managing a group of greenhouses.The process of sampling messages that quantify real-world physical circumstances and trying to convert the eventually results specimens into digital numeric values which can be modified by a computer is known as data acquisition.Lintern et al. (2020) proposed a wireless environmental monitoring system for precision agriculture and environmental monitoring industries to achieve real-time environmental monitoring and dynamic early warning.Kansanga et al. (2019) pointed out that the agricultural Internet of Things includes three layers: information perception layer, information transmission layer and information application layer.Douthwaite et al. (2017) used sensor and information fusion technology and Internet technology to design an agricultural information platform covering the whole country, and formed a hierarchical system structure for the collection, monitoring, transmission, processing and release of agricultural information.

Construction of an eco-agricultural tourism attractions management system based on the concept of circular economy
Based on the design concept of the Internet of Things, this paper combines the current development status of agro-ecological parks to apply the Internet, big data, cloud computing and image recognition and other cutting-edge mainstream technologies to establish an intelligent integrated management system for modern agro-ecological parks based on the Internet of Things.Agritourism gives tourists with experiences them to straight recognise the characteristics of local food even while integrating the social component of local food, suggesting that there are family members and small farms behind local food.Agritourism also encourages more people to spend a lot more money on local foods.Users can log in to the cloud platform directly through a computer or view the status of the park through an APP designed and developed for mobile devices such as mobile phones and tablets, and manage the entire park.The specific structure of the entire system is shown in Figure 1. Figure 1 illustrates the process of adaptive irrigation system where the information is collected in the next 3-5 days then it is feed into irrigation programming system for identifying the weather forecast and actual weather.Then it performs the irrigation process.
Adaptive agronomy technologies include smart irrigation and automatic mulching.That is, through the comprehensive park crop growth, soil moisture, park environment, etc., Agriculture agronomy is focused on producing plants with greater nutritional value and greater crop yields underneath a wide range of environmental conditions.Crops could be specially bred to achieve.Crop adaptation mainly refers to relationships between significant environmental factors and agricultural plant response.This life science branch, which really is mainly eco-friendly in environment, could be assumed of as a synthesising of important aspects of geographic location, physiology, genetic factors, atmospheric science, and agronomy.Smart irrigation technology determines the landscape's irrigation requires using weather information or soil moisture data.Smart irrigation technology consists of the three products, these products optimise irrigation productivity by minimising wastage of water while preserving plant health and the quality.Mulching is the process or practicing of trying to cover the ground in terms of improving plant life, advancement, and agricultural production effectiveness.Mulch is a technological term that means soil covering.automatic irrigation and automatic mulching management of crops are realised, as shown in Figure 2. At the same time, the weather forecast is incorporated into the irrigation and mulching control, so that corresponding decisions can be made in advance according to future weather changes (Adat et al. 2017;Vangala et al. 2020).
The entire adaptive irrigation system integrates weather forecast data obtained from authoritative weather stations into the system on the basis of existing automatic irrigation.In addition to making real-time irrigation decisions based on soil moisture, crop growth, and real-time environmental conditions, the system can also integrate future weather changes, automatically adjust irrigation procedures, and make irrigation plans in the next few days in advance.When the actual weather conditions are quite different from the forecasted weather, the system will make corresponding adjustments to the preset irrigation programme.The specific process is shown in Figure 3 (Tong et al. 2019).
As shown in Figure 4, the automation exhibition hall (management room) and the on-site remote communication relay module realise wireless data transmission and control through GPRS.The expansion of GPRS is General Packet Radio Service.General Packet Radio Service is a packet-oriented cellular data requirement used on the universal mobile telecommunications communication systems of 2G as well as 34 g cellular networks.One of the primary goals of GPRS is to make things easier to communicate a mobile phone to certain other packet-switched channels, which opens a door to the internet world.With the emergence of packet mode, mobile communications and the Internet combined to create mobile Broadband technology.The on-site remote communication relay module transfers the data collected by the short-distance wireless data transmission module through the radio frequency short wave.The gate valve well substation in the pilot area is installed at the branch pipe.Remote communication refers to the communication and through digital communication, convention telephone, teleconference, the web, or any other implies by which individuals who are just not present physically in the same place can interact with others considerably all at the same.According to the different requirements of sprinkler irrigation and drip irrigation, high-performance  The adaptive film mulching technology accurately analyses the future environmental weather, and then adjusts and arranges the corresponding film mulching procedures in the next few days according to the growth conditions of different crops in the park, which fully guarantees the demand for crop growth.In the cold season, the mulching film starts acting as a warm air and cooler insulating material; mulch helps to prevent land from quickly freezing, and that in the summer, it helps maintain soil temperature.Mulching acts as a barrier between both the land and droplets, trying to slow the coastal erosion (Gupta et al. 2021).Among them, the growth status of crops is mainly determined by image recognition technology and data collected by other terminals in the park.The specific process is shown in Figure 5 (Easterly III and Myers 2017).
In the park, observation points are set up for each crop planting area, and each observation point includes trapping equipment such as video monitors, pest inducing boards, and insecticidal lamps.Under normal circumstances, the monitor is used to collect the growth of plants in the area and the working conditions of automated equipment.At regular intervals, the monitor monitors and captures the pest induction equipment at fixed points, and transmits the collected field information to the pest monitoring and early warning system after being processed by the controller.The system calculates the occurrence rate and occurrence index of various diseases and insects, and displays the survey statistics in real time on the GIS map, which intuitively reflects the damage degree of the diseases and insects in each region.Incidence rate and occurrence index refer to the incidence rate and disease index for diseases, and the occurrence rate and insect situation index for pests.Users can view the corresponding early warning information through smart agriculture APP software on mobile devices such as mobile phones and tablets.If no one takes measures to eliminate pests within a certain period of time, the system will take

R E T R A C T E D
corresponding measures to control the occurrence of pests and diseases and ensure the healthy growth of crops.The specific implementation process is shown in Figure 6.

Leisure farm classification has a variety of categories in different standards and methods, and there are several common classification methods.There are numerous pest control methods from which to choose, and they can be widely categorised into six groups hygienic, biological, pesticide, physiological, filtration, condensation, and thermal treatment (Mangalraj et al. 2020).( 1

connotation as an agricultural landscape.At the same time, avoiding duplication of construction and project mini, and has a characteristic ecological agriculture that has its own characteristic ecological agriculture.(5) Brand and benefit principle brand is the soul of enterprise development, and the development of ecological agriculture also needs to continue to develop and improve their own brands.In the course of the planning and construction of the ecological agricultural project, we must make full use of relevant theories and methods, set the brand strategic awareness, create a corporate image, create high-quality tourism environments, and improve tourism images to achieve fermented economic benefits.
Eco-agriculture projects generally go through a fivestage process of analysis, positioning, layout, planning, and development.Under the guidance of the introduction of the related theory of the integration of the agricultural Internet of Things, the vertical process focuses on the stage of the agricultural Internet of Things planning, and the horizontal development also integrates the needs of the agricultural Internet of Things.In terms of leisure and entertainment, the experience of agricultural Internet of Things is emphasised, and agricultural Internet of Things technology is also involved in industrial production.The ecological agriculture project process that integrates the agricultural Internet of Things is more complete and specific, more scientific and reasonable.Figure 7 shows the project flow chart.
'Agricultural Ecological Demonstration Are + Agricultural Tourism' is based on rural areas as the main carrier, organised by rural collectives, and taking advantage of the rural natural ecological environment.Based on agriculture, it combines ecological agriculture demonstration with agricultural tourism to develop tourism.The emergence and development of this model have played a significant role in the improvement of rural economic levels, the improvement of farmers' living environment, and the green development of agriculture.Moreover, it promotes the mutual promotion and public development of agriculture, ecology, and tourism, and brings huge economic, ecological and social benefits.The eco-agriculture demonstration zone is a relatively independent and open to the outside of the complex ecosystem, which combines natural, social, and economic attributes, and focuses on the coordinated development of the internal

R E T R A C
T E D subsystems of the system and the internal and external systems.Among them, ecological agriculture is the focus of the ecological demonstration area, and the rural area is an important form of the ecological agriculture demonstration area.A certain level of human development, inventive abilities and skills, conveyed in types and forms of living and formed universal values, which is characterised by a deep and overall awareness of environmental issues in the complexities of humanity, Culture of the Ecosystem.Starting from the goal of developing 'big agriculture', the eco-agriculture demonstration zone implements the planning and overall planning of agriculture, forestry, animal husbandry, by-product processing industry, and fishery based on the principle of overall coordination.Moreover, it promotes the coordination of all aspects of development, enables them to support and promote each other, and realise the rapid and healthy development of agriculture.In addition, it protects the rural ecological environment and achieves the unity of ecological benefits, social benefits, and economic benefits, as shown in Figure 8.With the continuous expansion of the construction scale of the agro-ecological park, the variety of crops in the park will continue to increase.However, many crop tourists can't distinguish clearly, and it will even cause great distress to park managers.Therefore, it is necessary to establish a two-dimensional code traceability system for tourists in the park (as shown in Figure 9), and paste the corresponding crop identification twodimensional codes on various plants in the park.After that, the user only needs to scan the QR code corresponding to each area with a mobile phone to clearly understand the relevant situation of the crops grown

R E T R A C T E D
in the area, recognise their growth habits, health benefits, etc. and the corresponding recipes.Figure 9, illustrates the system architecture of two-dimensional code traceability system, by QR code chasing the chase.Then it is categorised into visitor QR code traceability system and administrator QR code database and it finds the information of crop management planting method and crop-related cognitive information.Figure 9, illustrates the system architecture of twodimensional code traceability system, by QR code chasing the chase.Then it is categorised into visitor QR code traceability system and administrator QR code database and it finds the information of crop management planting method and crop-related cognitive information.Food safety issues are getting more and more attention from relevant departments and consumers.Moreover, from the field to the table, food will go through a complicated process.Therefore, to ensure the absolute safety of food, the process from planting, picking and processing to sales should be transparent.In order to ensure the safety and transparency of the food produced in the park, corresponding QR code labels are affixed to the packaged food.When purchasing, consumers scan the QR code on the product with their mobile phone, enter the query platform to query the identification label for basic information of agricultural products and related information of the park enterprises, and can feed back information to the system.This realises the supervision of the safety of agricultural products, which is conducive to the realisation and promotion of ecological agricultural products.The specific process is shown in Figure 10.

Effectiveness verification of the planning method of ecological agricultural attractions based on the concept of circular economy
Based on the concept of circular economy, this paper constructs a planning system for agricultural attractions, applies the Internet of Things system to the system, and builds an agricultural ecological attractions management model, and combines the actual experience of tourists in agricultural ecological attractions to construct an IoT module system.On this basis, this paper verifies the performance of the system constructed in this paper, and explores the planning effect of eco-agricultural tourist attractions.This article first evaluates the system's intelligence, verifies the system performance by means of expert scoring, and analyses the system performance in combination with the simulation test research method.In the system performance verification, 78 sets of data are used to explore the operating

R E T R A C T E D
effects of the data in the system to evaluate the intelligence of the system.The results obtained are shown in Table 1 and Figure 11.
Through the above analysis, we can see that the agricultural attraction planning system based on the concept of circular economy constructed in this paper can effectively improve the planning effect of ecological agricultural attractions.On this basis, the satisfaction survey results of the system constructed in this paper are analysed, and the statistical results are shown in Table 2 and Figure 12.
Through the above experimental analysis, it is further proved that the planning system of eco-agricultural tourist attractions based on the concept of circular economy has a certain effect.

Conclusion
In recent years, the continuous innovation of agricultural Internet of Things technology has brought many benefits to agricultural production, such as liberating productivity, improving production efficiency, and enhancing safety.In the case of repeated construction, no special features, and no breakthrough in overall planning and design in the development of ecological agriculture, it is urgent to re-plan and design ecological agriculture from the perspective of agricultural Internet of Things, so as to achieve the goal of improving the landscape and entertainment experience of ecological agriculture.Under the interactive guidance of the related theories of the Internet of Things, Agriculture, Tourism and Landscape, this paper combines agricultural production, agricultural landscape, agricultural tourism and agricultural Internet of Things, improves the overall planning and design level of ecological agriculture, realises the sustainable development of ecological agriculture, and promotes the development of agricultural tourism and modern agriculture based on ecological agriculture.Moreover, this paper improves the information management level of ecological agriculture and realises a better experience of modern information agriculture for tourists.In addition,
