滨江城市节水型社会评价指标体系研究

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

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。

Most of riverside cities are rich in water resources,but the pollution induced water shortage is often a restricting factor for the development of the cities. The construction of water- saving society can solve the water resources development bottleneck for riverside cities,so conducting objective assessment for the construction achievement is the basis of the related work. According to the social development and water resources characteristics of riverside cities,24 main related evaluation indexes are selected to compose 4 relative isolated evaluation groups,and with the comprehensive analysis and evaluation means of analytic hierarchy 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.
