哈尔滨市居住区雨水资源化与景观整合设计

The Integration Design of Residential Area Landscape and Rainwater Resources in Harbin

以哈尔滨市"颐源庭院"居住区景观设计为例,从雨水资源潜力分析、居住区雨水资源直接、间接利用景观途径3个方面详述了居住区景观与雨水资源化的整合设计策略。结果表明:颐源庭院5—10月可回收利用的雨水总量为14023.55m3、总消耗用水量为20129.54 m3,收集回用雨水量能够满足该居住区的部分用水;通过构建"雨水花园"及"花坛雨水收集利用模式",颐源庭院居住区可分别收集道路、绿地雨水资源7786.08 m3,屋顶雨水资源6985.03 m3。在居住区雨水资源化的同时打造出丰富的居住区景观,可为城市居住区雨水资源管理与景观的整合设计提供借鉴。

Selecting the Yiyuan Courtyard in Harbin as an example ,through the following three aspects：Potential analysis of rainwater resource ,the direct and indirect used landscape approaches of residential rainwater resources ,which detail the integrated design strat-egy of residential area landscape and rainwater resources.The results showed that：From May to October ,the total amounts of rainwa-ter recycled and reused is 14023.55 m3 and the total water consumption is about 20129.54 m3.The recycled and reused rainwater can meet the part of water consumption of the residential area ,which offers the possibility of reference for the implementation of rainwater collection and utilization of resources.By building “rainwater gardens” and “parterre rainwater harvesting mode”, roads, green spaces rainwater resources 7786.08 m3 and rooftop rainwater resources 6985.03 m3 can be collected separately in Yiyuan Courtyard residential area.In considering settlements rainwater resources while the rich settlements landscape is else built ,attempting to urban residential area rainwater resource management and the integration of landscape design provides reference .
