摘要: 以昆明市为例，结合城市不同片区的实际情况，采用自上而下的方法对海绵城市建设最主要的控制目标——年径流总量
控制目标进行分解细化。通过对昆明中心城区用地、土壤、地下水等基础资料的调查分析，提出昆明市海绵城市建设的总
体规划布局和年径流总量控制方案；结合历史降雨资料分析，提出不同年径流总量控制率所对应的设计降雨量，将不同分
区LID措施进行量化。研究表明，量化后的LID措施在新开发地块中实施难度不大，但在现状地块中要进行改造则具有较大
的难度,需要采取一些灵活控制措施。
Abstract: This paper takes the real situation of different areas of Kunming into considerations, employs a top-down approach, and decomposes
the main target of sponge city construction: annual runoff control rate. Based on the investigations of planned land use, soil
components and ground water table, a runoff control zoning is put forward and the corresponding design precipitations for each zone
are studied. Quantities of LID measures in different zones are also calculated to meet the runoff control requirements. The study
shows that it’s not difficult to implement enough LID measures in new developing area, but in developed area, it is hard and needs
more flexible policies to meet the requirements.
