摘要
以雨水、绿地和硬化面为研究对象,根据不同降水重现期来分析不同比例集水面面积比例和不同下凹深度的绿地对雨水的入渗和产流系数,通过数据计算和分析,得出比较明显的结果,采用下凹式绿地对滞蓄和入渗雨水效果显著,雨水资源利用的潜力巨大。
With the rainwater, greenbelt and hardened surface as study case, and according to the different precipitation scheduled time, the rainwater＇s infiltration and runoff modulus of different proportion collecting water surface area and different concave depth greenbelt are analyzed. Then, the comparatively obvious result is obtained by calculating and analyzing the data that the effect on sluice-stopping and infiltration rainwater is distinct by adopting concave greenbelt, and the potential of rainwaterusing is enormous.
