唐山市城市地表径流量分析

Analysis on Tangshan Urban Surface Runoff Volume

在水资源匮乏的北方地区，城市雨水利用是缓解水资源紧缺的一种有效途径。通过对唐山市城市产流回流分析，唐山市平均每年雨水资源量为4265万m3。如何有效利用城市雨水资源，对雨水收集、雨水处理和雨水利用三个方面进行了分析，可为生态城市建设和城市雨水利用提供科学依据。

For the lack of water resources in North China, urban rainwater utilization is an efficient way to ease water resource shortage. By ana- lyzing Tangshan urban runoff production and backflow, the average annual rainwater resource of Tangshan is 42. 65 million m3. The paper analy zes rainwater collection,rainwater treatment and rainwater utilization in order to efficiently utilize urban rainwater resources,which can provide scientific basis for ecological urban construction and urban rainwater utilization.
