A STUDY ON THE PLANKTON COMMUNITIES IN THE SOUTH HUANGHAI SEA AND THE EAST CHINA SEA

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.
