城市复杂建成环境下绿色基础设施对雨水径流的水质水量影响及规划布局研究

Review of Water Quality and Quantity Performance and Planning Layout of Green Infrastructure Under Complex Built Environment in Urban Areas

本文比较了美国城市典型绿色基础设施的建成环境,以及其对水质水量的影响,通过分析纽约和费城城市范围内绿色基础设施建设的案例,提出绿色基础设施在中国城市建设的意见和建议:(1)与灰色基础设施的改建相结合,因地制宜,选择合适的设施和布局,促进路边绿色基础设施在城市中的建设;(2)双管齐下,同时推进绿色基础设施在公共区域和商业区域的建设;(3)重视绿色基础设施定期维护,制定相应的维护规范;(4)长期监测、科学管理,着手建立全国性的数据库,搭建中国城市绿色基础设施布局和数据管理平台。

This paper compares the built environment, water quality and quantity performance of typical green infrastructures in the US, and reviews case studies of city-scale green infrastructure projects in New York City and Philadelphia to propose following suggestions for green infrastructure built in urban areas in China.（1） Combine the green infrastructure project with gray infrastructure retrofit plan. Select types and layouts of green infrastructure based on the local situation. Impel the right of way green infrastructure development.（2） Implement green infrastructure on both public and private lands.（3） Make maintenance manuals of green infrastructure, and maintain the green infrastructure both periodically and as needed.（4） Monitor longterm water quality and quantity data, start to build national-wide database for stormwater management.
