摘　　要：应用Mann-Kendall非参数统计检验法和有序聚类法分析了清漳河流域1956年-2008年径流量的变化特征。分析发现径流量系列呈显著性下降趋势，且1977年为显著突变点。通过对径流量的影响因素定量分析发现，清漳河流域径流量的变化是降水量和人类活动共同影响的结果，且降水量的影响程度大于人类活动影响。Applying the Mann Kendall non-parametric statistical inspection method and sequential cluster method, the article analyzes the runoff variation in Qingzhang River basin from 1956 to 2008. The result shows that the runoff series is significantly decreased, and 1977 is the signifi-cant mutational year. Through the quantitative analysis to its influencing factors, the article finds that the variation of runoff is the joint effect of precipitation and the human activities, and the influence of precipitation is greater than the human activities.
