| 摘 要： | 利用Mann-Kendall突变检验法对延河流域1952—2008年降水量与甘谷驿站径流量进行分析,并以1952—1994年为基准期,定量分析1995—2008年降水变化和人类活动对径流的影响。结果表明:57年来延河流域正常降水发生概率达80.7%,径流年型以偏枯和枯水年为主;年降水量和径流量均呈减少趋势,突变分别发生在1995和2005年;与1952—1994年相比,1995—2008年的降水量和径流量较基准期分别减少11.1%和27.3%;降水变化和人类活动对径流减少的贡献率分别为46.2%和53.8%。

| Abstract: | Based on the observational precipitation and streamflow data in the Yanhe River basin during 1952-2008,the Mann-Kendall test was applied to investigate the trends of precipitation and streamflow.The effects of precipitation change and human activities on streamflow were quantified during the period of 1995-2008.The results indicate that the normal precipitation year accounted for 80.7 %,and most years were charactered by lower and low flow.Annual precipitation and streamflow both exhibited decreasing trends... |
