The Study On The Coupling And Coordinated Development Of Agricultural Economy And Agroecological Environment And Its Influencing Factors In Shandong Province

As a basic industry in our country,agriculture is the foundation on which other industries develop,and is also an important guarantee for our country’s food security.The No.1 Central document continuously focuses on the issues of "agriculture,rural areas and farmers",pays more attention to agricultural development,attaches more importance to food security,and keeps the rice bowl firmly in its own hands.The report also proposed to promote green development,promote harmonious coexistence between man and nature,accelerate the green transformation of development mode and achieve high-quality development.At present,the agricultural development of our country has begun to enter the transition stage.The relationship between the agricultural economy and the ecological environment has become a hot topic in the field of sustainable development and a hot topic paid attention to by the academic circle.Good ecological environment is the basis of agricultural development,which can provide the basic material living conditions needed for agricultural production,but at the same time in the process of agricultural development will cause certain damage to the ecological environment.With the continuous development of agriculture,chemical fertilizers,pesticides,mulch and other chemical products are used in large quantities,the ecological environment is increasingly damaged,the environmental carrying capacity is weakened,and the quality of agricultural products declines.Therefore,studying the harmonious relationship between agricultural economic development and ecological environment has important significance for realizing regional green development,and then provides theoretical support for realizing ecological protection and high-quality development in the Yellow River Basin,so as to realize the sustainable development of agriculture in our country.As the downstream province of the Yellow River Basin,Shandong Province has a good foundation for agricultural development.Therefore,it is of great significance to study the coupling and coordinated development relationship between agricultural economy and agro-ecological environment in Shandong Province for the realization of agricultural green development and overall high quality development in the Yellow River Basin.This paper classifies relevant literatures on the coordinated development of agricultural economy and ecological environment,takes the concept of sustainable development and the theory of resource carrying capacity as the guidance,takes Shandong province as the research object,and establishes the evaluation index system of agricultural economy and agricultural ecological environment in Shandong province through the analysis and research on the coupling coordination level of agricultural economy and ecological environment in Shandong Province.Thus the comprehensive evaluation index of the development of the two systems is obtained.The coupling coordination degree model is used to analyze the coordination development level and spatio-temporal evolution law of the two,and the geographic detector model is used to detect the factors affecting the spatial differentiation of the coupling coordination development.The results are as follows:(1)From 2000 to 2020,the coupling coordination level of agricultural economy and eco-environment in Shandong Province has been on the rise on the whole,and the coupling coordination type has changed from mild dissonance to near dissonance,from ecological priority economic backward development type to economic priority ecological backward development type.In recent years,the development of the two is relatively balanced,and gradually began to adjust to coordinated development.(2)The coordinated development of agricultural economy and ecological environment is greatly influenced by resources and environmental carrying capacity,agricultural input and agricultural output,and there is a synergistic effect among the driving factors.Therefore,according to the analysis results,suggestions are put forward from the aspects of adjusting industrial structure,changing planting pattern and rational investment,so as to promote the coordinated development of agricultural economy and ecological environment and take the road of green and sustainable development.
