1855年以来黄河河口已经历了10余次大型改道,1950年以后改道3次。由于黄河口多次改道,尾闾往复摆动,黄河泥沙在河口大面积淤积(占总来沙量的20％),形成了现代黄河三角洲。黄河口的演变对河口海区的理化和生物环境均产生了一定影响。本文主要根据1959年农业部黄海水产研究所等单位和1984年中国科学院海洋研究所的调查资料(沈志良等,1989;李全生等,1986;任广法,1987),对黄河口1964年和1976年两
Since 1855, the Yellow River estuary has undergone more than 10 major diversions and three diversions since 1950. Due to the repeated diversions of the Yellow River estuary, the tail wagging back and forth, the Yellow River sediment deposition in the estuary a large area (accounting for 20% of the total sediment), forming a modern Yellow River Delta. The evolution of the Yellow River estuary has a certain impact on the physical and chemical and biological environment of estuaries. Based on the survey data of the Yellow Sea Fisheries Research Institute of Ministry of Agriculture in 1959 and the Institute of Oceanology of Chinese Academy of Sciences in 1984 (Shen Zhiliang et al., 1989; Li Quansheng et al., 1986; Ren Guangfang (1987)), this paper analyzes the Yellow River Estuary in 1964 and 1976
