Spatial coupling relationship between economic poverty and ecological vulnerability in Beipanjiang River Basin,Guizhou Province
In order to study the spatial coupling relationship between economic poverty and ecological environment in Beipanjiang River Basin and reveal its spatial pattern,based on remote sensing data and statistical data,the evaluation system of economic poverty and ecological vulnerability of township units in Beipanjiang River Basin is constructed.The spatial pattern and coupling characteristics of economic poverty and ecological vulnerability are comprehensively analyzed by using the coupling coordination degree model.The results show that:1)The villages and towns with moderate poverty account for 40.54%of the total villages and towns in the study area.The villages and towns with severe poverty are mainly distributed in the southeast,the middle of the study area and the northwest of Liupanshui.2)The spatial distribution of ecological vulnerability is obviously different,and the degree of ecological vulnerability becomes more and more serious from east to west.The villages and towns with moderate or above vulnerability only account for 30.41%of the total villages and towns,and the ecological vulnera-bility is at a low level.The distribution of various types has obvious concentration.3)The type of cou-pling and coordination accounts for 83.24%of the whole township,which is in a good state of coupling and coordination.The types of coupling coordination differences are distributed contiguously and inten-sively,and the types of maladjustment differences are mainly distributed in the eastern part of the study area.The research can provide some theoretical support for regional economic development and environ-mental improvement,and provide scientific reference for regional sustainable development.
