不同雨洪管理目标下的城市公园绿色雨水基础设施选用研究

Selection of Green Stormwater Infrastructure in Urban Parks under Different Stormwater Management Goals

摘要:

为研究在不同雨洪管理目标下城市公对绿色雨水基础设施（GSI）的选用现状以及其偏好特征，搜集了伯明翰铁路公园等 20 个采用 GSI 建设的城市公园案例，按照公园的雨洪管理目标和 GSI 措施类型对其进行分类统计。结果表明：城市公园在 4 种雨洪管理目标下的 GSI 措施选用差异并不明显，都倾向于选用蓄水池、生物滞留设施和雨水湿地 3 种 GSI 措施；同时，在雨水资源利用和雨水景观营造 2 种目标下，城市公园也倾向于增加对渗管/渠型 GSI 措施的应用。

Abstract:

In order to study the current status of Green Stormwater Infrastructure(GSI) measures adopted by urban parks and their preference characteristics under different storm management goals, 20 cases of urban parks using GSI, such as Birmingham Railway Park, are classified and counted according to storm management goals and GSI measures. The results show that there is no obvious difference in the selection of GSI measures for the four types of storm management goals in urban parks, and three GSI measures of reservoirs, bioretention and constructed wetlands are preferred. At the same time, under the two goals of stormwater utilization and stormwater landscape construction, urban parks also tend to increase the application of infiltration pipe/canal GSI measures.
