| 摘要: |
| 下凹式绿地具有蓄渗雨水、削减洪峰流量、过滤水质和防止水土流失等优点，是城市雨洪利用的重要措施之一。对在设计暴雨条件下凹式绿地的蓄渗、减洪效果进行了分析计算，结果表明：在1倍汇水面积的情况下，对于10，50和100年一遇的暴雨，下凹式绿地的降雨拦蓄率分别为87．15％，58．48％和50．75％；其减峰率分别为71．04％，46．82％41．525；蓄渗、减洪效果极为明显。 |

| Analysis of Rian Storage and Infiltration in Sunken-lawn Under the Condition of Designed Storm |
|
|
|
| Abstract: |
| Sunken lawn have the advantage of storing and infiltrating the rainwater, cutting down flood flow and peak, filtrating water quality, preventing soil erosion and beautifying the environment, etc. It is one of effective measure of rainwater use in town. The effects of storage and infiltration is calculated and analyzed under the condition of designed storm. Results showed that it is very effective. It is suggested that the sunken lawn is adopted in program and construction of town. |
| Key words: sunken lawn,design storm,rainwater storage and infiltration rainwater use |
