滨江城市节水型社会评价指标体系研究

滨江城市大多水资源丰富,但水质型缺水往往成为制约城市发展的重要因素。建设节水型社会是滨江城市破解水资源发展瓶颈的主要方法,而对节水型社会建设成果进行客观评价是开展相关工作的基础。根据滨江城市社会经济发展及水资源的特点,通过评价指标遴选,筛选出20个评价值,组成4个相对独立的评价指标模块,并选取层次分析法作为综合分析评价手段,构建滨江城市节水型社会评价指标模型。以江阴市为实例,应用所建立的评价体系进行了评价。结果表明江阴市节水型社会达到了优秀的水平。这与江阴市2015成为全国节水型社会示范区的实际情况一致,说明所构建的评价体系科学合理。

Study of evaluation indicator system of water-saving society for riverside cities

Most of riverside cities are rich in water resources, but the pollution induced water shortage is often a restricting fac-tor for the development of the cities. The construction of water-saving society can solve the water resources development bottle-neck for riverside cities, so conducting objective assessment for the construction achievement is the basis of the related work. Ac-cording to the social development and water resources characteristics of riverside cities, 24 main related evaluation indexes are se-lected to compose 4 relative isolated evaluation groups, and with the comprehensive analysis and evaluation means of analytic hi-erarchy process ( AHP) , the evaluation model for water-saving society construction of riverside cities is established. The model is applied in Jiangyin City in Yangtze River Basin. The evaluation result shows that the city has reached outstanding-level in construction of water-saving society, which is consistent with the actual situation that it became a national demonstration city in water-saving society construction in 2015. So, the evaluation model is scientific and reasonable.
