本文应用NOAA卫星图象,分析黄河入海泥沙的扩散形态。经研究后发现,黄河入海口位置不同,入海泥沙的扩散形态亦不同。1976年后,黄河在清水沟附近入海,此处黄河泥沙的扩散形态有明显的扩散边界,绝大部分入海泥沙沉降在边界以内,黄河口南北两侧,不存在强烈的沿岸泥沙流,所以目前黄河泥沙对河北、山东沿岸港口无直接影响。
In this paper, NOAA satellite imagery is used to analyze the diffusion patterns of sediment into the sea. The study found that the Yellow River into the sea at different locations, the proliferation of sediment into the sea is also different. After 1976, the Yellow River entered the sea near Qingshuigou, where the diffusion pattern of sediment in the Yellow River has obvious diffusion boundary. Most of the sediment entering the sea has settled within the boundary. There is no strong sediment flow along the north and south sides of the Yellow River mouth , So at present, the Yellow River sediment has no direct impact on the ports of Hebei and Shandong coasts.
