中小城镇节水型社会建设模式研究——以海城市为例

Pattern for constructing water-saving society for medium-sized and small towns—taking Haicheng City as an example

从节水型社会建设的内涵着手,将中小城镇的节水型社会建设模式分为工业型、农业型、旅游服务业型、生态退化型及卫星型城镇等5类,并给出推荐模式形式。以海城市为例探讨中小城镇具体的建设模式。其中利用层次分析法探求合理的用水比例途径;提出可持续污水处理模式并给出框架;探讨利用经济手段促进节水,提出节水型水价概念。

The implication of water-saving society construction for medium-sized and small towns was analyzed in this paper. The pattern of constructing water-saving society was classified into five types： the industrial type, the agricultural type, the tourist and service industrial type, the environment degradation type and the satellite-type town. The forms of these models were described in this paper. Taking Haicheng City as an example,the patterns of constructing water-saving society model were examined. The analytic hierarchy process method was used to find the rational way of utilizing water, the mode and frame of sustainable wastewater treatment were proposed, the economic measure for enhancing water-saving efficiency was discussed, and the concept of water-saving pricing was also suggested.
