Ecological vulnerability assessment based on AHP-PSR method and analysis of its single parameter sensitivity and spatial autocorrelation for ecological protection – A case of Weifang City, China

With the continuous development of society, the contradiction between human and nature becomes increasingly prominent, and ecological vulnerability assessment is an effective tool to alleviate the contradiction. In this study, AHP-PSR (Analytic Hierarchy Process - Press-State-Response) model was use...
