基于AHP和GRA的江阴市节水型社会建设综合评价

Comprehensive evaluation of water saving society construction in Jiangyin City based on AHP and GRA

从节水效率、节水管理、节水保障、创新性工作4个方面,建立了江阴市节水型社会评价指标体系,并对其节水型社会建设进行了阶段划分。运用层次分析法确定评价指标权重,结合灰色关联分析法建立了江阴市节水型社会建设综合评价模型。结果表明:江阴市节水型社会建设总体已处于优秀阶段,其中工业用水重复利用率、水平衡测试率、节水型载体覆盖率、地表水功能区水质达标率、地下水管理水平处于良好阶段,城市供水管网漏损率和用水定额达标率仍处于中等水平,城市再生水回用率还只是初级阶段。研究结果可以科学反映江阴市节水型社会建设水平,并指导节水型社会建设工作的进一步实施,同时对其他城市建设节水型社会也具有一定的借鉴意义。

The water - saving society evaluation index system of Jiangyin city was established from four aspects of water saving efficiency, water saving management, water saving protection and innovative work, and the construction of water saving society has also carried on the stage division. Through the determination of the weight of evaluation index by AHP, a comprehensive water saving society construction evaluation model based on the grey relational analysis method was established in Jiangyin city. The results showed that： the construction of water- saving society in Jiangyin had been generally in excellent stage. The industrial water recycling rate, water balance test rate, water saving carrier coverage rate, surface water quality compliance rate of functional areas and groundwater management level were all in good stage. The leakage rate of city water supply pipe network and water quota compliance rate were still at a medium level. Urban regeneration water reuse rate was only at the primary stage. The results can scientifically reflect the level of water saving society construction in Jiangyin City, guide the further implementation of water - saving society construction object, and also have reference significance for other cities building watersaving society.
