黄河每年输沙11亿吨,其中36％漂浮于渤海,其余64％淤积在下游及河口三角洲地区。大量泥沙的堆积使得三角洲推进迅速,平均每年为25km。相当部分的悬浮泥沙由河口向外输送,对三角洲本身及邻近地区的工农业生产、交通和人民生活都产生不同的影响。本文主要根据1983年冬季和1984年夏季对黄河口及邻近海区观测分析的结果来讨论黄河泥沙入海后的迁移和季节性的差异。
The Yellow River annually discharges 1.1 billion tons of sediment, of which 36% float in the Bohai Sea, with the remaining 64% silting in the lower reaches and estuarine delta areas. The accumulation of large amounts of sediment makes the delta advance rapidly, averaging 25km per year. A considerable part of the suspended sediment transported out of the estuary will have different impacts on the industrial and agricultural production, transportation and people’s livelihood in and around the delta itself. This paper mainly discusses the migration and seasonal differences of the Yellow River sediment into the sea based on the results of the observation and analysis of the Yellow River Mouth and its adjacent sea areas in the winter of 1983 and the summer of 1984.
