针对地下储水空间雨洪利用的优先选址问题,采用层析分析手段,构建了包含3个层次8项指标的评价指标体系,制定了评价标准,确定了指标权重。在此基础上,采用模糊综合评价法,针对不同指标类型,分类构造隶属度函数,最终构建起地下水储水空间雨洪利用适宜性综合评价模型。实际应用表明,本指标体系与评价方法计算方便,可操作性强,在地下储水空间雨洪利用适宜性评价方面进行了有益探索。 Aiming at the problem of preferential location of rainwater and flood utilization in underground water storage space, a system of evaluation indexes including 8 indexes of 3 levels is constructed by means of the chromatographic analysis. The evaluation criteria are established and the index weight is determined. Based on this, fuzzy comprehensive evaluation method is adopted to construct the membership function according to different index types. Finally, a comprehensive evaluation model for the suitability of rainwater and flood in groundwater storage space is constructed. The practical application shows that the index system and evaluation method are easy to calculate and maneuverability, and beneficial exploration is made in the evaluation of suitability of rainwater and flood in underground water storage space.
