摘要
通过实际测量和计算,对2005年长沙市区城市绿地需水量和输入水量进行了平衡分析,旨在为长沙市城市绿地雨水资源利用提供科学依据。分析结果表明,2005年长沙市区绿地总需水量为4.587×108m3,降水入渗量为4.486×108m3,缺水0.101×108m3。综合上述结果以及长沙市年均降水量等因素,长沙市区绿地缺水形势严峻。
Through measurement and calculation,a water balance analysis of water requirement and water input of green space was conducted in Changsha City in 2005,which aimed to provide scientific references for rainwater utilization in green space in Changsha City.The results showed that total water requirement and precipitation infiltration amount of green space in Changsha City were 4.587×108 m3 and 4.486×108 m3,respectively.The water deficit was 0.101×108 m3.It could be concluded that the green space in Changsha City was in a serious situation of water shortage.
