新自然主义草本植物景观在城市雨水花园中的应用与设计

The Application and Design of the New Naturalistic Herbaceous Planting in Urban Rain Gardens

如何设计结构稳定、功能高效的可持续城市雨水花园植物景观,做到低投入、少人工管理并拥有更佳观赏价值,是城市园林设计师亟待解决的问题。本文针对目前雨水花园植物设计中存在的问题,探讨了新自然主义草本植物景观在城市雨水花园中的应用前景。针对雨水花园生境与洼地结构中水湿因子的时空分布特征,讨论了适应性选种策略。结合对自然群落"有序的混乱"的生命智慧的分析,阐述了师法自然的雨水花园植物群落设计思路。

Landscape architects are responsible for ensuring the structural stabilization and the high-efficiency of the ecosystem services of plantings in urban rain gardens, and also adapt more attractive rain garden plantings with requiring less inputs for their establishment and maintenance. In this paper, we address the existing problems of the planting design in the current rain garden applications, and introduce the idea of the new naturalistic herbaceous planting for upgrading urban rain gardens, We provide the design of the new naturalistic herbaceous rain garden planting by explaining the plant selection for satisfying the dynamic moisture distribution in rain garden habitat and the ＂disciplined chaos＂ strategy for establishing attractive plant community by learning from the nature.
