摘  要:
下凹绿地是一种简单的城市雨水蓄渗技术,该技术简单易行,工程投资少,效果好。下凹绿地的蓄渗量随下凹深度、绿地率增加而增加。根据天津市实际情况,经实验测试及理论计算得出,在绿地下凹100mm,绿地率为30%时,对1年一遇和2年一遇的雨水可达70%的蓄渗率,可以有效减少雨水洪峰量,增加地下水资源,同时减少绿地用水量。

摘  要:
Concave-down green space is a simple rainfall collection technique in urban setting.It has advantages such as simplicity,low investment and high efficiency.The storage and infiltration efficiency can be improved with increases of the depth of concave and the area of green space.According to the actual situation in Tianjin City,the experimental tests and theoretical calculations suggested that the depression depth should be 100 mm in the environmental setting of Tianjin City.With 30% green space rate,the storage-infiltration efficiency could reach up to 70% for the storms with recurrence interval of 1 or 2 years,which will reduce the flow peak and at the same time,minimize effectively the water demands of green oases and increase ground-water resources.
