摘　　要：为分析丹江口水库工程对下游河流径流情势的影响,以汉江皇庄站为研究站点,采用IHA法计算分析了丹江口水库修建前后水文特征值的变化。结果表明,丹江口水库的修建对汉江径流情势有明显的改变,除极值出现时间变化幅度较小外,其他各组水文特征值变化显著。该研究为评价人类活动对河流生态系统的影响提供了依据。To analysis the influeuce of river flow regime by Danjiangkou reservoir, this paper takes the Huangzhuang hydrological stations on the Hanjiang River as the case study sites; and uses the IHA method to evaluate the effect of Danjiangkou Reservoir. The results revealed that the flow regime of hanjiang have changed obviously as well as other hydrological feature values except the timing of annual extreme water conditions. The output of this paper can provide reference for the assessment of impacts of human activities on the Yangtze River ecosystem.
