杭州城市绿地生物滞留设施的植物现状与优化策略——以高位花坛为例

Plant Application Status and Optimization Strategies of Biological Retention Facility in Hangzhou Urban Green Space:Taking High Flowerbed as an Example

生物滞留设施是海绵城市建设的重要低影响开发雨水设施之一,具有较强的适用性及观赏性。作为生物滞留设施代表之一,高位花坛在海绵城市建设中发挥着一定的作用。植物对高位花坛设施功能的发挥尤为关键,目前高位花坛在我国相关理论研究及设计实践应用较少,且对高位花坛中植物的研究匮乏,有待深入研究。文章对实地调研案例中高位花坛设施植物的应用种类、频次、配置结构、观赏特性以及养护管理等方面进行分析,结合分析结果,从植物的选择、配置效果、养护管理等方面提出了相应的优化策略,以期为相关研究提供借鉴。

Bioretention facilities are one of the important low-impact development rainwater facilities in sponge city construction,with strong applicability and ornamental value.As a representative bioretention facility,high-level flower beds play a certain role in sponge city construction.Plants are particularly critical to the function of high-level flower beds.At present,high-level flower beds are rarely used in relevant theoretical research and design practice in China,and the research on plants in high-level flower beds is lacking,which needs further research.This paper analyzes the application types,frequency,configuration structure,ornamental characteristics and maintenance management of high-level flower bed facility plants in the field research case.Combined with the analysis results,the corresponding optimization is put forward from the aspects of plant selection,configuration effect,maintenance management,etc.strategy in order to provide reference for related research.
