自然力驱动的景观化海绵城市水系统构建

Construction of Landscape Water System of Sponge City Driven by Natural Forces

针对上海市临港沪城环路海绵化改造项目建设,阐述其设计思路及应用实践。以满足海绵城市建设相关指标为出发点,综合考虑科普教育、参与互动及示范展示等功能需求,进行整体景观提升及整个地块的水环境、水生态系统的构建。在保持原有地形地貌基本特征不变的前提下,对场地进行整体梳理。将道路雨水引入两侧绿地,利用生物滞留设施进行滞蓄、渗透及净化处理,并与绿地内原有水体联通,共同构建一套完整的、重力驱动的雨水消纳净化系统。同时,构建太阳能驱动的水体循环系统、风能驱动的富氧曝气系统、生物能驱动的水体净化保质系统、人力提水净化互动展示系统等以自然力驱动的水环境、水生态系统。多系统协同打造可观赏、可游憩、可体验、低维护的海绵城市改造示范段。

In view of the construction of the Shanghai Lingang Hucheng Ring Road Sponge City Reconstruction Project,the design ideas and application practices are expounded.Taking the relevant indicators of sponge city construction as the starting point,the functional needs such as popular science education,participation in interaction and demonstration are comprehensively considered.The overall landscape improvement and the construction of water environment and water ecosystem of the entire land are carried out.Under the premise of keeping the basic characteristics of the original topography and geomorphology unchanged,the site is combed as a whole.The road rainwater is introduced into the greenbelts on both sides.The bio-retention facilities are used for depot storage,infiltration and purification treatment,and are connected with the original water bodies in the greenbelt to jointly construct a complete gravity-driven rainwater absorption and purification system.At the same time,the solar-powered water circulation system,wind-driven oxygen-enriched aeration system,bio-energy-driven water purification and quality assurance system,and manpower water purification interactive display system are constructed as the water environment and water ecosystem driven by natural forces.The multi-system synergy creates a demonstration section of the sponge city reconstruction that can be viewed,recreational,experienced and low maintained.
