中文摘要:

随着我国城市化进程的快速推进和海绵城市理念的不断加深，低影响开发（LID）措施日益受到各地重视。为评估LID措施的雨洪控制效果，构建基于SWMM的东濠涌流域城市雨洪模型，分析选取适合该研究区域的LID措施，分别采用重现期为0.5、1、2、5、10年的设计降雨对LID措施的雨洪控制效应进行分析。研究结果表明：LID措施能够较为有效地减小流域洪峰流量、径流量及推迟峰值时间，对初期雨水径流污染负荷也具有较好的削减作用，且径流量和污染物削减率均随着重现期增大而减小。

英文摘要:

With the rapid progress of urbanization in China and the deepening of the concept of Sponge City, Low Impact Development (LID) measures have attracted more and more attention all over the country. In order to evaluate the effect of flood control on LID measures, the urban flood model of East Ho Chong watershed is constructed based on SWMM model. Then the suitable LID measures are selected for the study area, and the flood control effect of the LID measures is analyzed by using the design rainfall with the return period of 0.5, 1, 2, 5, and 10 years. The results showed that LID measures can effectively reduce the peak flow, runoff and delay the peak time. They also had good effect on reducing pollutant loads of first flush runoff, and the runoff and pollutant reduction rate decreased with the increase of the return period.
