以南京某小区为研究区域，采用暴雨洪水管理模型，模拟研究区域进行下凹绿地和透水路面改造后对区域内地面径流情况的影响。模拟结果表明，下凹绿地和透水路面均可有效消减地面总径流量和峰值流量，减小径流系数，同时改善研究区域的地下水环境。通过进一步改变下凹绿地和透水路面在模型中的规模后可知：下凹绿地面积占小区总面积的比例不应低于30％；透水路面面积占总面积的比例不应低于20％。
以南京某小區為研究區域，採用暴雨洪水管理模型，模擬研究區域進行下凹綠地和透水路麵改造後對區域內地麵徑流情況的影響。模擬結果錶明，下凹綠地和透水路麵均可有效消減地麵總徑流量和峰值流量，減小徑流繫數，同時改善研究區域的地下水環境。通過進一步改變下凹綠地和透水路麵在模型中的規模後可知：下凹綠地麵積佔小區總麵積的比例不應低于30％；透水路麵麵積佔總麵積的比例不應低于20％。

Taking a district in Nanjing as study area, using the management model of storm and flood, the paper studied the effect reconstruction of sunken lawn and porous pavement on surface runoff in study region.The simulation results showed that both concave down greenbelt and permeable pavement can ef-fectively reduce the total surface runoff, peak flow and runoff coefficient, meanwhile it can improve the environment of groundwater in study regional.Through changing the scale of sunken lawn and porous pavement in the model, the conclusion was gotten that the ratio of the sunken lawn area to total area shall not be less than 30%;the ratio of the porous pavement area to total area shall not be less than 20%.
