农村人居生态环境质量评价体系构建研究OA

The quality of China's rural human settlement ecological environment urgently requires improvement,and the lack of a comprehensive evaluation index system and methodology poses a significant challenge.Consequently,developing a tailored evaluation framework is critical for advancing rural human settlement ecological environment quality.This study con-structs an evaluation system for rural human settlement ecological environment quality using the Pressure-State-Response(PSR)model and determines indicator weights through the Analytic Hierarchy Process(AHP).The PSR model results demonstrate that the evaluation system consists of 14 indicators,including 5 pressure indicators,5 state indicators,and 4 response indicators.AHP analysis reveals that the weights for pressure,state,and response indicators are 0.154,0.573,and 0.273,respectively,with state indicators serving as the dominant factor.At the operational level,green coverage rate(0.197),sanitary toilet penetration rate(0.124),and domestic sewage treatment rate(0.104)exhibit the highest im-pacts on rural human settlement ecological environment quality,as reflected by their respective weights.This study establi-shes a theoretical foundation for evaluating and enhancing rural human settlement ecological environments.
