主　　题：Low impact development Rainwater harvesting Non point source pollution reduction Campus 

摘      要：Building a rainwater system based on the idea of low-impact development （LID） is an important aspect of the current ＂sponge city＂ construction in China. The ＂sponge city＂ concept emphasizes that the runoff can permeate the soil or be stored temporarily, and rainwater could be used again when it is needed. Beijing is one of the earliest cities to study rainwater harvesting and LID techniques in *** long-terua monitoring of rainfall, runoff flow, and water quality of a campus demonstration project in Beijing, the runoff quantity and pollutant concentration variations have been analyzed. Furthermore, the runoffreduction effects of single LID measure, such as green roof, filtration chamber, and permeable pavement, have been investigated. Additionally, the overall reduction effectiveness of the LID system on the average annual rainfall runoff and pollution load has been discussed.
