基于水资源保护的城市可持续水系统景观策略研究——以场地尺度景观实践为例

从对水资源保护的角度出发,阐述了场地尺度中,城市可持续水系统设计的景观策略,并以美国华盛顿运河公园的水系统设计和西德维尔友谊中学人工湿地景观两个已运行项目为案例,分析了场地尺度的水系统设计的概念和方法,阐明场地设计应关联水供应和水需求,就地合理储存、利用雨水和再生水,建立节水景观,以实现场地水平衡的目标,并提高场地生态、教育、文化、休闲等价值。

Landscape Planning and Design Strategy Research on Urban Sustainable Water System Based on Water Resource Protection--Case Studies of Landscape Practices in Site Scale

From the perspective of water resource protection, this article elaborates the landscape strategy in sustainable urban water system through the site scale. Through case studies of the Washington Canal Park and the artificial wetlands of Sidwell Friends Middle School, this article analyzes the design principle and methods for the water system. The site design should associate with water supply and water demand; make storage, treatment and suitable reuse of stormwater and wastewater available onsite. Establish water-saving landscape and achieve water balance. Improve the eco, educational, cultural and recreational value in landscape.
