城市节水绿地系统规划研究——以哈尔滨哈西区为例

Study on planning of urban water saving greenfield system

为了将雨水资源化利用与绿地系统规划相结合给区域节水绿地的建设提供理论依据,最终达到节约城市淡水资源的目的,以哈尔滨市哈西区为切入点,对研究区的雨水资源潜力展开研究;利用GIS地表水文分析技术,将能够收集雨水的区域确定为节水绿地,进而对哈西区的绿地系统进行规划设计。对我国目前的城市雨水资源化利用的现状、研究区的特点及其节水绿地的规划、绿地系统的结构与布局等方面的情况作了介绍。

To combine urban rainfall resource utilization with greenfield system planning and lay theoretical foundation for the construction of regional water - saving greenfield that aims at saving urban fresh water resources, we select Haxi District of Harbin as the subject and study the potential of local rainfall resources. The zones able to collect rainfall were identified as water - saving greenfield by using surface - water hydrological analysis technology of GIS, based on which the greenfield system of the district was planned and designed. The status quo of rainfall resources utilization in China, the characteristics of the study area, and the planning, structure and layout of its water - saving greenfield system are introduced.
