城市滨水区域“可呼吸式”植物配置及养护模式初探——以上海黄浦滨江公共空间为例

Preliminary Study of the Breathing Plant Arrangement and Maintenance in Urban Waterfront:A Case Study of Huangpu Riverside Public Space in Shanghai

城市滨水是城市中最宝贵的生态景观资源,滨水区域绿化植物配置及养护的优劣直接影响城市滨水空间景观面貌及生态效益。为提升城市滨水区域植物配置,通过分析上海黄浦滨江公共空间植物配置及养护实践案例,探索“可呼吸式”植物配置和养护模式。“可呼吸式”植物配置以自然、通透、韵律为特点,可通过合理配置植物层次、花境式植物,搭配运用岩石等造景元素以及合理降低植物种植密度等方法进行实施。植物选择上,注重色叶树种、特色灌木、宿根花卉、观赏草、乡土植物等,体现“可呼吸式”植物配置特点。后期植物养护中,通过自然式修剪、适应性及养护评估、无公害病虫害防治等实施要点,促进达成低碳与资源节约、可持续性植物景观维护以及生态环境保护的理念和要求。以期为城市滨水区域植物配置及养护提供理论依据与实践基础。

The urban waterfront presents the most precious ecological landscape resources in the city.The arrangement and maintenance of garden plants directly affect the landscape and the ecological benefit of the urban waterfront.In order to improve the plant landscape in the urban waterfront,this study discussed the case of Huangpu River Public Space for the mode of breathing plant arrangement and maintenance.The breathing plant arrangement is characterized by a natural,transparent and metrical style.It can be realized by reasonable gradation of plant arrangement,floral border arrangement,reasonable use of rocks and other landscape elements,reasonable reduction of plant density,etc.As to plant selection,the application of colored-leaf trees,characteristic shrubs,perennial flowers,ornamental grass,and indigenous species is highlighted to enhance the role of the breathing plant arrangement.In the course of plant maintenance,natural trim,assessment of adaptability and maintenance,pollution-free disease,and insect pest control are the key point for the concept and requirements of low carbon and resource conservation,sustainable plant landscape,and ecological environment protection.The study aimed to provide theoretical and practical proofs for the plant arrangement and maintenance on the urban waterfront.
