城市雨水廊道公园的设计探究——以武汉玉龙河公园为例

Exploration on the Design of Urban Rainwater Corridor Parks:A Case of Wuhan Yulong River Park

在我国中部、南部降雨量较多的城市,随着城市的发展,城市原有的自然水文特征被改变,城市内涝问题愈演愈烈。在城市大面积绿地区域,打破原有硬质渠道或管道排水方式,依据城市原有的汇水地形并设计形成城市雨水廊道,依托其周边绿地打造生物栖息地,进而规划形成城市雨水廊道公园是解决问题的有效手段。本研究以玉龙河公园为例,基于水系、海绵设施、景观布局及植物种类分析,设计了兼顾排水、生态、景观复合功能的城市雨水廊道公园,提出了雨水廊道公园的概念,最终总结了城市雨水廊道公园的设计方法。

In China’s central and southern cities with more rainfall,with the development of the city,the city’s original natural hydrological characteristics are changed,and urban flooding problem is getting more and more serious.In the large green areas of the city,breaking the original hard channel or pipeline drainage,forming the urban rainwater corridors by design according to the city’s original catchment topography,creating a bio-habitat based on the surrounding green space,and then forming the urban rainwater corridor parks by planning is an effective means to solve the problem.The paper takes Yulong River Park as an example,and then based on the analysis on water system,sponge facilities,landscape layout and plant species,designs an urban rainwater corridor park that takes into account the composite functions of drainage,ecology and landscape,puts forward the concept of rainwater corridor park,and finally sums up the design methods of urban rainwater corridor park.
