生态水质净化技术在城市湿地公园设计中的应用以长广溪国家城市湿地公园一期景观设计为例

摘要

Taking the landscape design of Chang Guang Xi River National Urban Wetland Park as an example, this paper introduces three ecological water filtration methods-gravity filtration system,flow-balancing filtration system and settlement-overflow filtration system-and analyzes the design, construction, the one-year water quality monitoring data and the 5-year operating and maintaining conditions after open-up of the mentioned methods. Based on the construction implementation cost, filtration effects and maintenance conditions, this paper first gives an analysis of the features, advantages and disadvantages of each method. It then explores the possibilities of the integration of the methods and landscape design according to the analyzed features and requirements, fol owed by a conclusion of the advantages and disadvantages of the application of each filtration method in landscape design. Technical detection parameters and landscape ecological design references to similar landscape design projects wil be given at the end of this paper.%以长广溪国家城市湿地公园一期示范段景观设计为例，通过该项目应用的3种生态水质净化技术--重力过滤系统，廉布过滤系统，沉淀溢流过滤系统--的设计、施工、及运行一年后获得的水质监测数据、向公众开放五年来的运行和维护状况，进行总结分析。首先就建设实施造价、净化效果、后期维护等方面，分析每种水质净化技术的特性以及优劣势；其次，针对每种技术的特性和要求，探索其与景观设计有机融合的方法；最后，总结3种生态水质净化方法在景观设计应用中的利弊，为今后类似的景观设计项目提供技术检测参数和景观生态设计方法参考。
