中文摘要:

为研究径流对不透水面扩张的响应，通过建立沩水流域中上游HSPF模型，构建研究区2000-2015年不透水面扩张情景，探究该区域径流对不透水面扩张的响应。结果表明：HSPF模型月流量模拟精度较高，在本研究区有良好的适用性；在2000-2015年研究区不透水面扩张情景下，研究区不透水面扩张会引起年径流深小幅增长，不透水面扩张对枯水期径流深的影响大于对汛期径流深的影响，且不透水面扩张对枯水年径流深的影响最大，平水年次之，丰水年最小；相较于整个研究区，主城区与研究区不透水面扩张对径流深的影响在趋势上是一致的，但是主城区的影响程度比研究区大。

英文摘要:

In order to study the response of impervious surface expansion on runoff, this paper establishes the HSPF model in the upper and middle reach of the Weishui River Basin, and constructs impervious surface expansion scenario from 2000 to 2015. The results showed that the HSPF model has high precision on monthly runoff simulation, and is feasible in the studing area. The impervious surface expansion of the studying area will cause a small increase in annual runoff. The impact of impervious surface expansion on runoff during dry season is greater than that on runoff during flood season, and the impervious surface expansion has the greatest impact on the annual runoff depth of dry years, followed by the flat water years and the smallest in wet years. The runoff response of the impervious surface expansion in the main urban area is consistent with the trend of the whole study area, but its response is more severe than that of the whole study area.
