| Under the great opportunity of the party and the state to vigorously promote and develop the ecological civilization strategy,it is a new era to change the development path of traditional Chinese agriculture,improve the environmental pollution caused by traditional agricultural production,destroy the ecological environment and improve the economic benefits of traditional agricultural production.Based on a large number of literatures and comprehensive research on the status quo and trends of circular agriculture development at home and abroad,this paper believes that the current transformation of traditional agricultural traditional pathways is an important issue for agricultural production,but what kind of agricultural development model and how to choose appropriate agricultural pathways to promote The sustainable development of regional agriculture is an urgent problem to be solved.This study is based on the research on the sustainable development of agriculture in traditional agricultural areas.The main purpose is to clarify the sustainable development of agricultural systems under different agricultural development paths in traditional agricultural areas,establish a methodological system for studying regional agricultural development paths,and explore regional agriculture.The optimal path for sustainable development provides a scientific basis for the rational development,industrial planning,key decision-making and orderly management of sustainable agricultural development in traditional agricultural areas,in order to promote economic prosperity,social stability and ecological health sustainability in traditional agricultural areas..In this paper,the system dynamics method is used to carry out the system dynamics modeling and simulation research on the selection of agricultural development path in the typical traditional agricultural area-Jiade Township,Yaodu District,Linfen City,Shanxi Province,and the simulation results are comprehensively evaluated.The conclusions of this paper are as follows:(l)System dynamics simulation is a suitable method to study the agricultural development path.Based on the characteristics of system dynamics synergy,integrity,time-varying,dynamics,causality,limited data and various feedback relationships among various factors,the dynamic model of the development path of circular agriculture is constructed.It simulates the choice of agricultural development path in Jiade Township.Research suggests that the system dynamics method is a suitable method to study the agricultural development path.(2)Construct a methodological system for selecting agricultural development paths.The method system is mainly composed of the following parts:① Study the characteristics and trends of traditional agriculture and circular agriculture development;②Establish five agricultural development paths and 12 sub-paths of traditional agriculture,circular agriculture,and transmission-cycle;③The system dynamics models of five basic paths and their 12 sub-paths are constructed separately byusing system dynamics,.④The operating system dynamics models are used to obtain the operational results of different agricultural development paths.⑤The comprehensive evaluation method is used to evaluate the optimal agricultural development path.(3)Solving the problem of agricultural development path selection in traditional agricultural areas.Through the simulation study of Jiade Township,the development path of high-pass and low-cycle circular agriculture is the optimal path among the five basic development paths of Jiade Township;further research on system dynamics simulation and comprehensive evaluation shows that high transmission and low circulation The type I agricultural path of the path is the optimal sub-development path.The research method of agricultural development path in this paper not only solves the problem of agricultural development path selection in Jiade Township,but also provides a good solution for other traditional agricultural areas to choose agricultural development path.(4)The development of circular agricultural pathways according to local conditions can effectively promote regional sustainable development.Through the study,this paper believes that the comprehensive development of circular agriculture in the relatively backward traditional agricultural areas of the central and western regions is not the best choice,according to the regional development of circular agriculture,the level of agricultural technology,the recognition of farmers on circular agriculture,and the recycling of agricultural infrastructure.The degree of completeness and the policy level of regional development,and the adoption of a circular agricultural development path according to local conditions can effectively promote regional sustainable development.(5)Appropriate construction of circular agricultural projects promotes the smooth flow of regional circular agricultural pathways.Based on the study of the development model of the circular agricultural agricultural engineering construction in Jiade Township,this paper proposes three models of agricultural cooperatives to promote the circular agricultural engineering construction model,enterprise development to drive the circular agricultural engineering construction model,and the agricultural park to expand the circular agricultural engineering construction model.It is suitable for the construction mode of circular agricultural engineering facilities for Jade Township to go high,pass low and follow I cycle agriculture development path,and carry out quantitative research on various engineering facilities.Based on the quantitative research,the recent(2018-2025)and In the medium and long term(2026-2040),the construction and comprehensive layout of the circular agricultural engineering facilities in Jade Township strongly guided Jade Township to follow the path of I circular agriculture development to achieve sustainable development of regional agriculture. |
