中文摘要：

利用黄河入海控制站利津的实测水文资料及黄河流域的降水和人类活动影响的相关资料等，分析了近期黄河入海水量变化的特征及变化的原因。结果表明，1986年以来黄河入海水量大幅减少，断流现象突出等，与其以前相比，入海水量减少64％；在减少的水量中，“准自然因素影响”约占55％，引黄用水约占31．5％，其它人类活动影响约占13.5％。

英文摘要：

Based on the data of flow passing by Lijin Hydrometric Station, rainfall in the Yellow River basin, and human activities, the paper shows the feature of the flow regime change and the causes of formation. The research results show that the annual mean amount of flow coming to the sea since 1986 has decreased by 64%, which results in, among others, continuous flow cutoff in the lower Yellow River. Causing the decease in flow regime, quasi-natural factors contribute about 55%, water division about 31.5%, and the other human activities about 13.5%.
