Abstract

Abstract

During May 11 to May 15,1999,it was investigated in the Changjiang Estuary and adjacent areas in order to determine nutrient in these areas is the limiting factor of phytoplankton grouth.From the analyses on the distributions of phytoplankton,chlo rophylla,nutrients,temperature and salinity,as well as the result of field and laboratory experiments,it is known that Pis the limiting nutrient in the diluted areas and the limiting intensity is higher than that in November 1998.This is due to the volume and direction of the diluted water and the vertical steady state of water.This area is divided into four parts according to the limiting status of phytoplankton growth.Because this investigation was at the end of the spring bloom,the number of species and density of phy to plankton are much lower than that in November 1998.
