基于水土保持的长汀县农业生态经济耦合系统演变过程
Evolution process of agricultural eco-economic coupling system in Changting County based on soil and water conservation
摘要
Abstract
[Objective]The aims of this study are to reveal the coupling pattern and evolution process of agricultural ecosystem and economic system in Changting County under soil erosion control,and to provide scientific basis for further promoting the high-quality development of soil and water conservation in Changting County.[Methods]Based on the statistical yearbook and land cover raster data of Changting County from 1992 to 2022,the evaluation index system of agricultural eco-economic system in this region was constructed according to the evolution process of agricultural eco-economic system,and the coupling model was used to study the evolution process of agricultural eco-economic coupling system in Changting County.[Results](1)From 1992 to 2022,the comprehensive index of agricultural ecosystem and agricultural economic system in Changting County showed an overall upward trend.(2)From 1992 to 2022,the coupling degree of agricultural eco-economic system in Changting County was between 10° and 270°.The system transitioned from recession coupling to uncoordinated coupling,and then to the coordinated coupling and uncoordinated coupling.The whole coupling state evolved into an S-shaped curve.(3)From 1992 to 2022,the agro-ecological economic coupling system of Changting County experienced the evolution stages of regeneration development,limit development,coordinated development and limit development.Among them,1992-2000 was in the stage of regenerative development,2001-2002 and 2017-2022 were in the stage of extreme development,and 2003-2016 was in the stage of coordinated development.[Conclusion]According to the development trend of coupling degree,it can be seen that by optimizing agricultural ecological and economic measures,the system can break through the uncoordinated coupling and develop in a coordinated direction,and even eventually reach a good or superior stage of coordinated development and evolution.关键词
