利用InfoWorks ICM模型建立深圳市光明新区新城公园雨水管网模型，分别以检查井和雨水口作为模型的节点划分汇水区，分析不同的汇水区划分方式对公园出口流量模拟结果的影响。结果表明：在中小降雨条件下，汇水区节点选取对峰值流量模拟结果的影响不明显；在暴雨或特大暴雨的条件下，汇水区节点选取对峰值流量模拟结果的影响较大；与以检查井为节点的划分方式相比，以雨水口为节点的划分方式产流时间会有一定程度的推迟；在模型建立过程中应综合考虑研究目标、区域尺度和降雨特征等对汇水区进行合理划分。

The storm drainage system model of Xincheng Park in Guangming New District of Shenzhen was set up based on InfoWorks ICM model. In this study the catchment area was divided respectively according to manhole and gully, and its effect on flow simulation results of park outlet was analyzed. The results showed that the selection of node-type had no obvious effect on peak flow simulation result in the condition of light or medium rainfall, while for storm or heavy rainfall the selection of node-type had great influence on peak flow. Compared to catchment division based on manhole, runoff-yielding time producing was delayed by dividing the catchment area based on gully. Therefore, research goal, regional scale and rainfall characteristics should be considered in the process of modeling to reasonably divide the catchment area.
