Low regime of flow coming to the Yellow River estuary in the recent years and its causes of formation
近期黄河入海水量减少成因分析

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%.
