“海绵城市”背景下的城市湿地公园植物景观营造策略

Plant Landscape Construction Strategy of Urban Wetland Park under the Background of“Sponge City”

“海绵城市”是近些年为有效解决城市雨洪管理问题而提出的新概念,它能够通过城市中的基础设施例如城市内河、水系池塘、湿地公园等,实现多余雨水的渗透、吸收和释放。在这一理念的指导下进行城市湿地公园植物景观的营造思考,有着较为重要的现实意义。从“海绵城市”核心概念入手,全面阐述了园林植物在海绵城市建设中的重要性,进而分析了城市湿地的功能及作用、城市湿地公园在海绵城市建设中的价值以及不同类型水环境中植物景观的营造方法,认为湿地公园的深水区、浅水区、水边区、陆地区都有各自不同的立体环境条件,需要抓住湿地这一关键要素,根据具体情况做好植物品种的选择、搭配和养护问题,更好结合城市特质和“海绵城市”理念的要求逐步推进湿地公园的景观营造,以期为现有湿地公园的景观优化和新建公园的景观营造提供可资参考的建议。

“Sponge city”is a new concept put forward in recent years to effectively solve the problem of urban stormwater management.It can realize the infiltration,absorption and release of excessive rainwater through urban infrastructure such as urban inland river,water system of pond,wetland park.Under the guidance of this concept,it is of great practical significance to think about the construction of plant landscape in urban wetland park.From the perspective of the core concept of“sponge city”,the paper comprehensively expounded the importance of garden plants in the construction of“Sponge city”,and then analyzed the function and role of urban wetland,the value of urban wetland park in the construction of“Sponge city”and the construction methods of plant landscape in different types of water environment.It pointed out that deep water area,shallow water area,the border area and the land area had their own stereo environmental conditions.Wetland should be thought as a critical element,making the choice,arrangement and maintenances of plant varieties according to specific circumstances.Combination of urban characteristics and the requirement of“sponge city”concept,construction of wetland park landscape were promoted so as to provide suggestions for the existing landscape optimization of wetland park and the new park's landscape construction.
