中文摘要:
      对雨水进行吸纳和利用是海绵城市建设的初衷。以雨水资源为研究对象,构建了基于雨水资源化条件、雨水资源化可实施程度、区域生态环境状况、经济可行性与综合雨水需求率的海绵城市建设中雨水资源利用潜力评价体系,利用层次分析法与模糊综合评价法对海绵城市建设中雨水资源的利用潜力进行评价。以浙江省临海市海绵城市建设试点区为例,通过综合径流系数法计算出,该地区在实施海绵城市建设后可增加雨水资源利用量28.46×104 m3;通过运用评价体系对该区域雨水资源的利用潜力进行评价。评价结果表明:该区域雨水资源利用潜力为Ⅰ级,雨水资源利用潜力大,即雨水资源丰富且可实施条件充裕。这与综合径流系数法计算出来的结果有较好的一致性,说明评价体系具有一定的合理性。从而为其他开展雨水利用工作的区域提供了基础的评价方法和理论支撑,具有一定的工程意义。
英文摘要:
      The absorption and utilization of rainwater is the original intention of sponge city construction. Taking rainwater resources as the research object, a rainwater resource utilization potential evaluation system was set up based on rainwater resources conditions, the implementation degree of rainwater resources, regional ecological environment conditions, economic feasibility and comprehensive rainwater demand rate. The analysis method and fuzzy comprehensive evaluation method were used to evaluate the utilization potential of rainwater resources in sponge city construction. Taking the pilot zone of sponge city construction in Linhai City of Zhejiang Province as an example, the comprehensive runoff coefficient method can be used to calculate that the utilization of rainwater resources can increase by 28.46×104 m3 after the construction of sponge city. The utilization potential of rainwater resources in the region is assessed by using the evaluation system. The evaluation results show that the utilization potential of rainwater resources in this region is Grade I, and the utilization potential of rainwater resources is large, that is, rainwater resources are abundant and can be fully utilized. This is in good agreement with the results calculated by the integrated runoff coefficient method, indicating that the evaluation system has certain rationality. This provides a basic evaluation method and theoretical support for other areas where rain water utilization is carried out, and has certain engineering significance.
