摘　　要：本文根据1972～1987年间中国和南朝鲜的海洋调查资料,分析研究了渤、黄、东海海水透明度的分布特征和季节变化,并对其影响因子作了较为详细的讨论。渤、黄、东海海水透明度具有明显的地区差异和季节变化。其基本特征为:近岸和河口区透明度低;远岸和受外海水系影响区高。冬季低;夏季高。控制透明度分布和变化的主要影响因子有:风和潮流的搅拌作用、大陆径流、沿岸和外海流系、沉积物分布和海洋层化等。On the basis of oceanographic data measured by China and South Korea during 1972-1987, the distributions and seasonal variations of trancparency and their affectio() factors are analysed in the Bohai Sea, Yellow Sea and East China Sea.It is found that the trancparency is characterised by rigional variations, with being lower in the near coast and estuary and higher in offshore areas or the areas affected by offshore current systems. Seasonal variations of transparency are characterised by higher in summer and lower in winter. The main factors controlling transparency are the stiring actions of wind and tidal current, runoff, coastal and offshore current systems, sidement distributions and stratifications of water column.
