【摘要】 大学校园汇水面积大,雨水容易收集,若对雨水进行适当处理后再利用,将具有良好的环境和经济效益。天津市某大学在校园生态集雨区设计与建设实施过程中,建立了集植草沟、下凹式绿地、生态护岸为一体的生态雨水收集系统,以渗蓄和净化雨水、削减洪峰流量、减轻地表径流污染。以该大学校园雨水径流补充景观水系为例,介绍了绿色校园雨水利用的低影响开发(LID)措施,并利用WASP模型进行水质模拟,评估LID措施的预期效果,以期为校园雨水利用提供参考。更多还原

【Abstract】 Rainwater is easy to be collected in the university campuses for the huge catchment areas. If rainwater can be utilized,it will have good environmental and economic benefits. In the process of designing and building the campus ecological rainwater collection area in a university in Tianjin,the ecological rainwater collection system consisted of grass gully,concave greenbelt and ecological embankment was established,so as to infiltrate,store and purify the rainwater,reduce the peak flow rate and mitigate the pollution of surface runoff. Taking the rainwater runoff replenishing the landscape water system of the university as an example,the low impact development( LID) measures of rainwater utilization in green campus were introduced,water quality was simulated by using WASP model,and the expected effect of LID measures were evaluated,which desired to provide reference for rainwater utilization in campus.更多还原
