摘要
20世纪80年代以来,山东东鱼河流域径流出现显著减小趋势,本文运用Mann-Whitney-Pettitt突变点分析法和Mann-Kendall检验法对东鱼河流域降水量和径流量序列突变点进行分析,并通过弹性系数法和水文模拟法对气候变化和人类活动对东鱼河流域径流的影响过程及结果进行探讨。结果表明,人类活动是引起东鱼河流域径流量减小的主要原因。
Shandong Dongyu River basin runoff suffers from significant decreasing trend since the 1980s. In the paper, Mann-Whitney-Pettitt mutational site analysis method and Mann-Kendall test method are applied for analyzing precipitation and runoff sequence mutational sites in Dongyu River basin. The influence process and results of climate changes and human activities on runoff of Dongyu River basin are discussed through elastic coefficient method and hydrological simulation method. Results show that human activities are main reasons leading to runoff reduction in Dongyu River basin.
