摘要
城市化进程加剧,过度开发严重影响了生态系统,同时,水循环系统也发生了改变。采用PCSWMM模型来模拟天津大学新校区在2003—2012年间连续十年的降雨数据,分析讨论传统雨水管理系统与低影响开发雨水管理系统的差别,以及单独加载不同低影响开发设施的效果。研究发现对于小于4 h的降雨,滞蓄水性能最好的是集水箱,其次为生态滞蓄池和渗透铺装。采用低影响开发模式对水平衡和洪水控制效果明显,并且对短时间降雨效果更为显著。生态滞蓄池、渗透铺装、集水箱这3种设施在不同指标中都有突出表现。
The ecological system is seriously devastated with the increasing urbanization and overdevelopment, meanwhile, the hydrologic cycle system is changed. A numerical model, PCSWMM, was employed to run ten years＇ continuous meteorological data（2003-2012） for the new campus of Tianjin University in order to compare the difference between traditional stormwater management system and Low Impact Development stormwater management system, and assess the performances of these LID alternatives.The results showed that cistern system provides the largest storage, following by bio-retention and porous pavement for short duration events（4 hours）. The investigation of the five LID alternatives revealed that these LID alternatives function obviously in flood control and water balance, especially for short duration rainfall events. Besides, bio-retention, porous pavement and cistern system performed well in all indices.
