摘　　要：为了通过优化选址来提高当前海绵城市的源头控制效果,缓解用地紧张,同时降低建设难度、减少成本,以雨水花园为例,提出了一种基于GIS水文分析和叠加分析的建设用地适宜性评价方法,可用于识别和提取适合建设或改造雨水花园的区域。采用该方法,以镇江市某区域为例进行分析,结果表明,适宜雨水花园的建设用地面积约占总面积的19.4%;适宜用地主要以林地和草地为主,约占80%,主要分布在古运河入河口及岸边的带状绿地、研究区东部和东南部等未开发用地以及研究区中心地带政府办公用地内部绿地,主道路两旁区域分布也较多。利用GIS软件在优化指标和权重的基础上可较准确、快速地发掘场地特性,进行雨水花园的建设适宜性评价分析,将分析结果进行可视化和指数化呈现,为海绵城市规划建设的选址提供一定支持。In order to improve the source control effect of sponge city,alleviate the shortage of land,reduce the construction difficulty and cost by optimizing the site selection,a method for evaluating the suitability of construction land based on hydrologic analysis and overlay analysis of GIS was proposed in rainwater garden construction,which could be used to identify and extract the area suitable for construction or transformation of rainwater garden. The method was applied in an area of Zhenjiang City.It was found that the suitable construction area of rainwater garden accounted for about 19. 4% of the total area. The suitable land was mainly woodland and grassland, accounting for about 80%, mainly distributed in the ribbon green space in the estuary and on the bank of the ancient canal,the undeveloped land in the east and southeast,the green space inside the government office area in the central area of the study area,and the area on both sides of the main roads. On the basis of optimizing the index and weight,GIS software could be used to accurately and quickly explore the site characteristics,evaluate and analyze the suitability of rain garden construction,visualize and index the analysis results,and provide some support for the site selection of sponge city planning and construction.
