| 摘 要： | 近年来,随着海绵城市建设的推进,我国学者对于城市雨洪管理方面的研究日益加深。然而海绵城市的建设相关问题也日益凸显,首要问题就是对于城区大范围积水分析、水安全分析等技术相对薄弱,使得大范围海绵城市的建设流于形式。以宜良县建成区为例,查阅相关文献并对积水点实际调研。借助ArcGIS工具的强大功能对城区的各项指标进行综合分析,得出宜良县建成区水安全敏感区分布图,从而使得海绵城市建设可以根据各区域水安全敏感情况制定不同策略,对今后海绵城市的建设具有借鉴意义。

| Abstract: | In recent years,with the development of sponge city construction,the research on urban stormwater management by Chinese scholars has been deepened.However,the problems related to the construction of sponge city are becoming increasingly prominent.The principle problem is that the technology of water safety analysis for large-scale water accumulation in urban areas is relatively weak,which makes the construction of large-scale sponge city become a mere formality.Taking the built-up area of Yiliang County as an example,the relevant literature are reviewed and the water points are investigated.With the powerful function of ArcGIS tools,the comprehensive analysis of various indicators of urban area is carried out,and finally the distribution map of water security sensitive areas in built-up areas of Yiliang County is obtained,so that different stratigies could be formulated during the construction of sponge city construction can formulate different strategies according to the water security sensitive situation of each area,which is of significant reference for the construction of sponge city in the future. |
