摘　　要：9404,9410 ,9702及98074个航次对东海泥质和砂质沉积区总悬浮颗粒物的季节调查显示由于冷涡区海水的底层幅聚作用使得位于冷涡中心的111站悬浮物含量高且集中在底层 ;111站海水中悬浮物含量冬、春季高 ,夏、秋季低 ,而410站则是春、夏高 ,秋、冬低。东海悬浮物的垂向分布可归纳为4类 :上低下高型 ,上高中低下高型 。Based on data from field observation on sedimentary and hydraulic factors in East China Sea in April 1994, October 1994, February 1997 and July 1998, the converged sea water in bottom layer in cold eddy area causes higher concentration of total suspended matter(TSM) collected in the Cower layer at station 111 in Spring and Winter than that in Summer and Autumn, but there is a converse situation at station 410. Vertical distribution of TSM can be classified in four types: low in the upper layer but high in the lower layer; high in the upper and lower layer but low in the middle layer; low in the upper and lower layer, but high in the middle layer; uniform.
