Abstract

河川径流不仅是水资源重要的构成部分,也是自然界中水分循环的重要环节,径流量的变化直接影响区域特
别是干旱区水资源的开发利用。基于黄河中游上中下三个站点(河口镇站、吴堡站以及三门峡站)1919—2013年月径
流量资料,采用Spearman相关法、有序聚类法等方法分析黄河不同区间年、月径流量演变规律,揭示年径流量突变前
后径流量年内集中度和不均匀性差异。结果表明:黄河上游和中游径流量因人类活动作用具有明显趋势性减小,而
因气候作用表现出显著的阶段性。在径流量突变年份后,黄河上游径流量上游集中度降低,不均匀度减小,径流量年
内分配趋于均匀,但黄河中游地区径流量年季不均匀性反而增大。

Other Abstract

Runoff is the important water resource and element of hydrologic cycle.The change of runoff
directly affects the exploitation and utilization of water resources.Based on the data of monthly runoff from
1919to 2013of the three sites(Heleouzhen station,Wubu station and Sanmenxia station)in the middle reaches
of the Yellow River,we used modern statistical analysis methods such as Spearman correlation,Mann-
Kendall rank test,sequential clustering method,to reveal the change of concentration and inhomogeneity about
runoff.The results showed that the runoff of upstream and middle reaches of the Yellow River has reduced
because of human activity.Meanwhile the climate impact on the runoff showed the significant stage.
After runoff mutation,the concentration and inhomogeneity of runoff in the upper reaches of the Yellow River
have reduced,and distribution of runoff tends to be more uniform,but inhomogeneity of runoff in the
middle reaches of the Yellow River increases instead.
