Evaluation of ecological environment quality in Danba County based on PSR model
To understand the current eco-environment status in Danba County,this paper uses the PSR model framework and selects 15 factors,including population density,per capita GDP,road network density,elevation,slope,aspect,topographic relief,annual rainfall,annual average temperature,potential evapotranspiration,water conservation,water network density,disaster point density,land use,and vegetation coverage,to establish an evaluation index system.This paper uses the analytic hierarchy process to determine index weights,analyzes the spatial distribution of eco-environment quality in Danba County in 2022,and explores the main factors influencing the eco-environment quality of Danba County using geodetector.
