利用1987年夏季 (6～7月 )中国科学院海洋研究所“科学1号”船在东海考察的透光度资料 ,分析了透光度在东海的分布特征以及与东海陆架悬浮体运移的关系 ,结果表明 :(1)沿123 30′E北上的台湾暖流宛如一道屏障 ,将长江的悬浮物质阻挡在123 30′E以西 ;(2)长江口门北面的悬浮物质由于受到长江冲淡水转向和北上的台湾暖流的共同作用 ,难以继续贴岸南下 ;(3)台湾暖流和黄海暖流很可能是黄海沿岸流携带的悬浮物质不能继续向深海输运的主要原因 ,两支流似乎也起到了屏障作用 ,将悬浮物质阻挡在126 30′E以西和30 30′N以北 ;(4)温跃层的存在是底层高悬浮体含量的海水难以到达表层的主要原因
Based on the transmission data of “Science No.1” ship of the Institute of Oceanology, Chinese Academy of Sciences in the East China Sea in summer 1987 (June-July), the distribution of light transmission in the East China Sea and the relationship with the migration of the sediments in the East China Sea shelf are analyzed The results show that: (1) Taiwan’s warm currents north of 12330’E are like a barrier blocking the suspended matter in the Yangtze River to the west of 12330’E; (2) the suspended matter to the north of the mouth of the Yangtze Estuary is affected by the diversion of the Yangtze River’s red water and (3) The warm current in Taiwan and the Yellow Sea warm current are probably the main reason that the suspended matter carried by the Yellow Sea coast can not continue to be transported to the deep sea. The two tributaries also seem to play a barrier role , The suspended matter is blocked to the west of 12630’E and north of 3030’N; (4) The existence of thermocline is the main reason that seawater with low content of bottom layer can hardly reach the surface
