| 摘 要： | 海绵城市建设中，地质条件对低影响开发措施的布设具有重要影响。本次研究以武汉市都市发展区为研究对象，在充分收集和整理武汉市城市地质调查数据基础上，分析地质条件对海绵城市建设影响机制，根据地质条件的蓄水、渗水、净水三大功能选取地面坡度、地层岩性、第四纪覆盖层厚度、地下水涌水量、表层土壤污染程度、植被覆盖率、距地表水系距离7个指标建立评价体系，利用层次分析法计算各指标权重，并对各单指标进行分级评分，借助Mapgis软件对各指标数据进行叠加分析。结果表明：武汉市都市发展区大部分为海绵城市建设地质条件适宜及较适宜区，且地层岩性和地表水系为主要影响指标，低影响开发措施布设时应该考虑地质条件的渗水和蓄水特性。

| Abstract: | During the construction of sponge city, geological conditions always have an important influence on choosing suitable low impact development (LID) facilities. Based on the metropolitan development area of Wuhan City, the mechanism that geological conditions influence the construction of sponge city is analyzed through processing of the urban geological survey data. According to the abilities of water storage, seepage and purification, seven factors, including surface slope, formation lithology, Quaternary thickness, volume of groundwater, extent of soil contamination, vegetation cover rate and distance from the surface drainage, are chosen to build the evaluation systems. Each factor is weighted with the analytic hierarchy process, graded according to national standards or the situation in the study area, and stacked with Mapgis. The results show that most areas are suitable or comparatively suitable for sponge city construction. Formation lithology and the distance from surface drainage are two important influence factors, and the abilities of water storage and seepage should be also taken into account in deployment of low impact development facilities in sponge city construction. |
