海绵城市建设背景下的道路绿地设计策略

摘要

随着城镇化的快速推进，我国城市的建成区面积持续扩大、城市体量不断增长，与此同时城市也面临着严峻的雨水问题：一方面城市的地下水位在不断下降，水资源变得越来越紧缺，另一方面洪涝灾害频繁发生。因此，如何充分利用雨水资源将成为未来城市生态建设的重要目标。文章结合海绵城市建设的理念，着重从排水分流控制、汇水径流引导和蓄水优化利用的角度构建了城市道路绿地设计策略，以期为海绵城市建设背景下的道路绿地建设提供借鉴。%Built area of cities are growing with urban expansion under fast urbanization.In the meantime, rainwater problem is getting severe: lfood rages as underground water level declines. Rainwater management has become critical to ecological city development. With sponge city concept, the paper presents the road green space design strategy from rainwater drainage, runof, storage, and provides a reference for other cases.
