Study On The Coupling And Coordinated Development Of Agricultural Ecology And Agricultural Economy System In Guizhou Province

Agriculture is a basic industry among the primary,secondary and tertiary industries,the foundation of the national economy and the basis of all industries,and its development is directly related to farmers’ income growth,food supply and social stability.At present,China’s development has entered a new era of socialism with Chinese characteristics,and the development of agriculture has also entered a new period of transformation and quality upgrading,and the relationship between agricultural economic development and agricultural ecological environmental protection should be handled well.This article through to the system coupling,agricultural ecological system of agriculture and agricultural economic system three themes of literature,the coupling theory,sustainable development theory,ecological economy theory is applied to research and as a theoretical basis for the analysis of the collected in Guizhou province from 2011 to 2020,10 years of agricultural ecology and agricultural economic system index variable data as objective basis.By building a reasonable index system,using the information entropy method to determine the ecological agriculture and agricultural economic system of the index weight,according to the coupling model and coupling coordination degree model,analysis of Guizhou agricultural ecological system and the present condition of the coordinated development of agricultural economy system coupling,on this basis,using the indicators data,by building the index system of the dependent variable and observation variables,Multiple linear regression equation model was used to analyze the coupling efficiency of agricultural ecology and agricultural economy system.In order to understand the sustainability of agricultural development in Guizhou province and whether it achieves coordinated and orderly development with agricultural ecological environment while developing agricultural economy.The conclusions from the research and analysis are as follows: The agricultural ecosystem evaluation index of Guizhou province shows a trend of fluctuation rise in the whole analysis period,although there are some years in the middle of the evaluation index value decreased compared with the previous year,but the decline range is very small.The system evaluation index of agricultural economy showed a trend of steady increase during the analysis period from 2011 to 2020.Although the growth rate of evaluation index slowed down in some years,it still maintained a growing trend.During the analysis period,the stability of coupling degree between agricultural ecology and agricultural economy system in Guizhou province is very high,and the development is stable for a long time.The value of coupling degree fluctuates around 0.5 for a long time.In the analysis period,the value of coupling coordination degree between agroecology and agricultural economy system increased from 0.2815 to 0.6364,and the coupling coordination degree changed from low coupling coordination to high coupling coordination.The type of coupling coordination also changes from ecological priority to economic priority.Through multiple linear regression equation model,the coupling coordination efficiency level of agricultural ecology and agricultural economy system in Guizhou province was analyzed.The results showed that soil erosion control area,agricultural water conservancy input,total power of agricultural machinery,rural electricity consumption,the quantity of pigs,cattle and sheep and pesticide use had significant effects on the coupling coordination degree of agricultural ecology and agricultural economy system.Combined with relevant theoretical research results,aiming at the present situation of the coupling development of agricultural ecology and agricultural economic system in Guizhou Province,five policy suggestions were put forward to promote the coupling optimization of agricultural ecology and economic system in Guizhou Province: promoting agricultural green production technology and developing ecological agriculture;Land management according to local conditions,large-scale production;Carry on agricultural industry structure adjustment actively;Improve agricultural mechanization level,improve agricultural infrastructure.
