城市不同区域雨水利用模式及可利用量研究

Study on the Mode and Quantity of Rainwater Utilization in Different Urban Regions

为了缓解城市水资源短缺的状况可在城市各种区域采取相应的雨水利用措施。从下垫面分类、建筑物格局等角度考虑,针对城市几类典型功能区归纳符合各自特点的雨水利用模式,形成包括社区、学校、公园、机关与企事业单位院落以及城市景观湿地、季节性河道等区域的一套较完整的城市雨水利用技术体系,并以郑州为例,估算了城市各典型区域多年平均雨水可利用量。

Rainwater utilization is necessary to relieve the scarcity of water resources in urban area. According to the different types of underlying surface and building structure, this paper concluded the modes of rainwater utilization for several kinds of typical urban areas that had different functions, made the technical system of rainwater utilization for urban area, and then took Zhengzhou for an example to estimate the utilizable quantity of rainwater.
