我国许多城市洪涝灾害频发与水资源短缺的矛盾不断加深，融合“海绵城市”与国内外最新的雨洪管理理念建设下沉式绿地，实现防治内涝、水资源利用、景观美化的多重效益。基于北京《雨水控制与利用工程设计规范》，通过水量平衡法计算下沉式绿地的设计参数。在壤质砂土地区，绿地下沉率为50%，年径流总量控制率85%的条件下，绿地率为20%、30%、40%时，合理的下沉式绿地设计深度分别为200、120、75mm。最后介绍了下沉式绿地的竖向设计、景观美化、植物淹水时间的优化设计方法。

In many Chinese cities, the conflict of frequent flooding and water shortage got deeper, it is necessary to integrate the latest concept of ecological stormwater management and “sponge city” into the construction of sunken green space landscape, so as to realize multiple benefits including the flooding control, water resource utilization and landscaping. Based on Beijing “Code for design of stormwater management and harvest engineering”, through water balance method, the design parameters of sunken greenbelt is determined. In the loamy sand area, sink rate of green space is 50%, under the condition of the control rate of total annual runoff more than 85%, when the ratio of green space for 20%, 30%, and 40%, the proper sinking depth of sunken greenbelt are 200mm, 120mm, and 75mm, respectively. Final y, the article briefly introduces the optimum design of grading, landscaping, and plant waterlogging time.
