摘　　要：选取昆明某片区为研究对象,以截留全年50%总降雨量为目标,采用SWMM模拟研究LID措施与雨水调蓄池联合运行的效果。在0.5、1、2年一遇重现期下分别运行仅设雨水调蓄池和LID+雨水调蓄池两种方案,结果表明,LID+雨水调蓄池措施对径流总量、径流峰值均有明显削减作用,对污染物的截留量有显著提升,且截留效率随重现期的增加而减小;在目前设置参数下,LID措施对径流峰值的出现时间无明显影响。另外,设置LID措施可显著削减雨水调蓄池容积。Abstract： Taking a section of Kunming as the research object, SWMM model was used to simulate the effect of LID measures combined with stormwater detention tanks, and it was aimed to intercept 50% of the total annual rainfall. Two programs of only detention tanks and LID ＋ stormwater detention tanks were operated respectively in the return period of 0.5, 1 and 2 years. The simulation results indicated that obvious reduction effects of runoff volume and peak runoff were achieved by LID ＋ stormwater detention tanks, and there was a significant increase of pollution interception, and the interception efficiency decreased with the increase of the return period. Under the current setting parameters, LID measures had no obvious effect on the occurrence of the peak runoff. In addition, the volume of stormwater detention tank could be remarkably reduced by LID measures.
