| 摘 要： | 利用朱庄区域长系列水文资料,对径流量的年内、年际变化特征及变化趋势进行了分析研究,分析了人类活动影响引起下垫面变化导致径流变化的原因,估算了降水和下垫面变化对径流量的影响量。该区域径流量年内、年际变化较大;多年径流量系列呈减少趋势,尤其从20世纪70年代末以来径流量发生了显著变异;下垫面变化是径流量减少的主要原因。

| Abstract: | Based on a long time series of hydrological data in Zhuzhuang Reservoir Basin,the paper analyzes characteristics of monthly and yearly runoff changes and their trends.Reasons that underlying surface changes made by human activities lead to runoff changes are also elaborated,and impacts made by rainfall and underlying surface changes on runoff are estimated.The research indicates remarkable changes of both the monthly runoff and yearly runoff as well as a decreasing tendency of the runoff for past years.Sinc... |
