集水区为基础单元的城市水与绿网络规划探索

The Study of Urban "Water and Green" Network Planning Based on Watershed

城市水系廊道作为"海绵城市"概念下暴雨水管理体系的主体框架,在缓解城市暴雨水问题上扮演重要角色。而如今城市水系的规划仍延续传统的规划方法,在暴雨水管理方面存在很多欠缺和发展空间。本研究旨在探索从宏观之集水区,中观之水系廊道,到微观之绿色雨洪基础设施网络,结合以自然集水区为基础单元的暴雨水管理与城市水系廊道规划的方法。提出以自然为基底,集水区作为规划的基础要义,水系廊道作为连结系统与绿色雨洪基础设施网络的自然通道的"水与绿"网络规划模式。

Recently,urban stream corridor,as an essential framework of ＂ Sponge City＂ concept,plays a significant role in mitigating urban runoff and storm water problems. Yet it is somehow insufficient and has a great deal of improvement margin. This study thus,aims to improve and coordinate urban stream corridor with storm water management for future development through rational methods based on natural drainage and watershed from macro perspective to micro perspective,which includes the natural watershed,river and stream corridor and green storm water infrastructures network.
