基于多种生境的湿地植物景观营造实践——以杭州植物园水生植物区为例

Landscape Construction Practice of Wetland Plants in Various Growing Environments——A Case Study of the Aquatic Plant Area of Hangzhou Botanical Garden

以杭州植物园水生植物区建设为例,介绍了总体设计思路和湿地植物特色,探讨了在平静水体、流动水体和旱溪等水体形态中湿地植物的选择要点,不同光照条件下阳性、阴性湿地植物的景观应用,以及水位变化影响下湿地植物景观营造的具体对策。针对项目中水体面积较大、水源不稳定的问题,通过实践归纳出湿地植物在生态海绵中的多种应用形式。此外,针对改造项目中新建湿地植物景观面积不足的问题,提出了利用现状植物营造湿地植物景观的思路。

Taking the construction of the aquatic plant area of Hangzhou Botanical Garden as an example,this paper introduces the overall design idea and the characteristics of wetland plants,and discusses the key points of plant selection for wetland plants in calm water,flowing water,dry stream and other water forms,landscape application of negative wetland plants,and specific countermeasures for wetland plant landscape construction under the influence of water level changes.Aiming at the problems of large water area and unstable water sources in the project,various application forms of wetland plants in ecological sponges are summarized through practice.In addition,facing the problem of insufficient area of newly built wetland plant landscape in the renovation project,the idea of using the existing plants to create a wetland plant landscape is proposed.
