摘要: 利用累积距平、Mann-Kendall检验和有序聚类方法,对长江中游5个水文站1961-2014年径流量进行突变检验,并应用降雨-径流多元线性经验模型,定量评估长江中游气候变化和人类活动对径流量变化的贡献率。研究结果表明:径流量多年来呈线性减少的趋势,随降水量的变化而变化。径流突变点为1968年和2006年,1969-2005年枝城、沙市、监利、城陵矶和螺山站控制流域人类活动对径流变化影响的贡献率分别为85.68%、50.89%、84.78%、89.81%和68.39%;2006-2014年人类活动的贡献率分别为88.40%、59.47%、82.86%、80.03%、63.63%,人类活动的贡献率高于气候变化。

Abstract: The impacts of climate change and human activities on runoff in the middle reaches of the Yangtze River were investigated with four approaches:the cumulative anomaly method, Mann-Kendall test, ordered clustering method and multiple linear empirical model. It is found that runoff has slowly decreased linearly for many years with precipitation change. 1968 and 2006 were the runoff abrupt change years.From 1969 through 2005, the human activities in the catchments controlled by Zhicheng, Shashi, Jianli, Chenglingji and Luoshan stations had contributed 85.68%, 50.89%, 84.78%, 89.81% and 68.39%, respectively, to the runoff decrease.From 2006 to 2014, the human activities in the catchments had contributed 88.40%, 59.47%, 82.86%, 80.03% and 63.63%, respectively, to the runoff decrease. The contribution ratio of human activity is higher than that of climate change.

Key words: climate change, human activity, contribution rate, runoff, rainfall-runoff empirical multivariate linear model, the middle reaches of the Yangtze River
