Research on the Coupling Relationship Between Poverty and Fragile Ecological Environment——Analysis Based on 14 Counties(Cities)in the Alpine Agricultural Region of Qinghai-Xizang Plateau
Taking 14 counties(cities)in the alpine agricultural area of Qinghai-Xizang Plateau as the research object,this paper constructs the evaluation index system of economic poverty and ecological environment,and analyzes the coupling relationship between poverty and fragile ecological environment in the research area.The results show that:(1)The overall coupling coordination degree of fragile ecological environment and poverty in the alpine agricultural area of Qinghai-Xizang Plateau is increasing,and presents four different stages of disordered recession poverty mild lag,disordered recession ecological environment mild lag,over-adjusted poverty mild lag,and over-adjusted ecological environment mild lag under the influence of the policy adjustments and other factors.(2)From 2011 to 2018,the ecosystem-poverty coupling coordination D in the alpine agricultural region of Qinghai-Xizang Plateau increased from 0.312 0 to 0.642 9,and the type of coordination was transformed from the dysfunctional recession category to the coordinated development category.The results of the study can provide a reference for the regional economic development and sustainable development of Qinghai-Xizang Plateau.
