摘要
雨水是自然界水循环系统中的关键环节,对调节、补充区域水资源和改善生态环境起着极为重要的作用。笔者从资源型透水铺装、屋顶绿化、下凹式绿地及人工湿地4个方面,阐述了雨水径流的最佳管理措施(BMPs)在上海世博会绿地中的应用,分析了不同处理技术的特点。在综合分析各项技术的处理效果、占地面积、后续管理、景观效果和适用场所的基础上,认为资源型透水铺装和屋顶绿化具有较好的应用前景,下凹式绿地及人工湿地也具有一定的应用价值。
The rainfall,a key link of water recycle system in the nature,is very important for recruiting regional water resources and improving the ecological environment.This article illustrated the best management practices of rainfall run-off applied in the green-space of Shanghai World Expo from four aspects including pervious groundcover,roof greening,concave-down green space and artificial wetland,and the characteristics of different ecological treatment technology were analyzed.Based on the comprehensive analysis including treatment effect,land area,subsequent management,landscape effect,and applicable place,pervious groundcover and roof greening had better prospects,meanwhile concave-down green space and artificial wetland also had a certain value.
