１９８４年８月、１１月和１９８５年２月、５月，笔者在黄海南部和东海北部，即２８°～３４°Ｎ、１２７°Ｅ以西海域进行了初级生产力及其有关环境要素的调查研究，结果表明，浮游植物现存量、生产力和生理活性均为春、夏两季高，秋、冬依次降低．春、夏两季高值区多出现在跃层附近和水团交汇处；秋、冬两季由于水体的强列混合，各要素分布趋于均匀．真光带叶绿素ａ平均值四季均为沿岸水＞陆架混合变性水＞台湾暖流及黑潮水．初级生产力春季沿岸水最高，陆架变性水和台湾暖流水相当；夏季陆架变性水＞台湾暖流水＞沿岸水；秋、冬则为台湾暖流水＞陆架变性水＞沿岸水．文章还评估了年有机碳生产量，并结合同期调查的渤海和黄海北部的结果，评估了渤、黄、东海的年初级生产量和潜在渔业生产量．３个海区总年有机碳生产量约为１９８．９×１０６ｔ，总潜在鱼类生产量约为５．４×１０６ｔ．
In August, November 1984 and February 1985, in May 1985, the author conducted a survey on primary productivity and its related environmental factors in the southern Yellow Sea and the northern part of the East China Sea, ie, the waters west of 28 ° -34 ° N and 127 ° E, The results showed that the existing stocks, productivity and physiological activities of phytoplankton were high in spring and summer, autumn and winter in turn decreased. The spring and summer high-value areas mostly appeared near the thermocline and the water mass confluence. In autumn and winter, the water quality was strongly mixed, and the distribution of various elements tended to be uniform. The true light with a chlorophyll a average of four seasons are coastal water> shelf denaturalized water> Taiwan warm current and Kuroshio. The productivity of the primary productivity was the highest in spring, while that of the shelf degenerated water was similar to that of the Taiwan warm water. The summer shelf degenerated water> the Taiwan warm current> the coastal water; the autumn and winter were the Taiwan warm water> the shelf degenerative water> coastal water. The paper also evaluated the annual organic carbon production and evaluated the annual primary production and potential fishery production in the Bohai Sea, the Yellow Sea and the East China Sea in combination with the results of the Bohai Sea and northern Yellow Sea surveyed over the same period. The total annual organic carbon production of the three sea areas is about 198.9 × 106t, and the total potential fish production is about 5.4 × 106t.
