基于层次分析法的水环境维护效益评价研究OA

Currently,the evaluation indicators for the maintenance of the urban river and lake water environment in Beijing are rather singular and significantly influenced by subjective factors.In order to conduct a scientific and objective benefit evaluation and quantify the management effectiveness,the Analytic Hierarchy Process(AHP)was employed.Eleven evaluation indicators were established from three dimensions:water quality,maintenance and management,and social benefits.The weights of each indicator were determined based on expert opinions,and an evaluation system tailored for the benefits of urban river and lake water environment maintenance was constructed.Taking the urban river and lake water environment maintenance work in 2023 as a case study,a benefit evaluation was performed,and the evaluation result was rated as"good".Furthermore,suggestions were proposed to further enhance the benefits of water environment maintenance.
