城市调蓄湖体净水工程设计的思考——以贵阳市花溪湖为例

Analysis of water purification design for urban storage lake——Taking Huaxi Lake in Guiyang as an example

生态文明建设的大背景下,国内城市湖体工程的实施进入了一个快速发展阶段,湖体工程已经成为城市公园建设的基本要求。文章以贵阳市花溪湖体工程设计为例,分析设计条件及背景、工程设计理念与生态景观元素要点,探讨生态文明建设背景下的城市调蓄湖体净水工程设计的本质所在。具体设计了生态净化工程、生态驳岸工程、生态修复工程、监测预警工程、水利高度工程以及综合管理工程。花溪湖工程设计在满足城市防洪安全基本要求下,能够充分发挥社会、经济、景观和生态等综合效益,为今后城市调蓄湖体净水工程设计提供参考。

Under the development of the ecological civilization construction, the implementation of urban lake project in China has entered a rapid stage, and the lake project has become the basic requirement of the urban park construction. In this paper,taking Huaxi Lake in Guiyang as a case, the design conditions and background, engineering concept and key elements of ecological landscape are analyzed, and the essence of urban storage lake engineering design for water purification under the background of ecological civilization construction is discussed. Specifically, ecological purification project, ecological revetment project, ecological restoration project, monitoring and early warning project, water conservancy height project and comprehensive management project are designed. The design of Huaxi Lake project can obtain the comprehensive benefits of society, economy, landscape and ecology under the basic requirements of urban flood control and safety, and provide a reference for the design of urban lake water purification project in the future.
