| 摘 要： | 下凹式绿地不仅能很好地解决城市内涝问题，还能补充地下蓄水。通过水量平衡分析得到了不同条件下下凹式绿地的渗蓄能力，并利用对临界绿化率的计算得到了要达到零地表径流所需的绿化程度。最后，根据天津市实际情况分析下凹式绿地的可行性。

| Abstract: | The concave-down green space can not only solve the problem of the urban waterlogging satisfactorily, but can also recharge the groundwater. Through a water balance analysis, the infiltration capacities of the concave-down green space under various conditions are obtained, and then the greening degree necessary for reaching the zero of the surface runoff is got with the calculation made on the critical greening rate. Finally, the feasibility of the concave-down green space is analyzed herein in accordance with the actual condition of Tianjin. |
