南黄海和东海浮游生物群落的初步探讨 总被引：10，自引：5，他引：10
南黄海和东海位于中国东部的陆架上,这个区域受江河迳流、大陆沿岸流、黄海冷水和黑潮水的影响,明显地反映出其水文、化学要素、浮游生物的分布都比较复杂.如果仅从浮游生物组成看,有暖温带的近海种,有半咸水河口种,有沿岸低盐种;也有外海热带种.它们构成了浮游生物各自的群落分布区,在群落之间由于水团的水平和垂直方向不同程度的混合,存在着一个群落交汇区.群落及其交汇区具有相对的稳定性,但随季节而有变化.本文根据1960年和1971年对南黄海和东海(东经127°以西、北纬27°-34°)进行渔场环境调查时,所获得浮游生物的样品,经分析后提出以下的初步探讨. 相似文献

The South Huanghai Sea and the East China Sea lie on the east continental shelf ofChina. These areas are generally under the effects of river, coastal currents, and coldwater in the Huanghai Sea, as well as the branches of Kuroshio. Therefore, obviously, thephysical oceanography, chemical elements and plankton distribution in these areas areconsiderably complicated. As for plankton composition, there are temperate neriticspecise, brackish water and estuarine species, coastal species and also tropical pelagicspecies. Each community of the plankton occupies a distributional area of its own.Among the communities there exists a transitional area caused by horizontal andvertical mixing of water masses which effect this area in different degrees. All commu-nities and the transitional area are more or less relatively stable, except for seasonal varia-tion. 相似文献
