Estuarine and coastal eutrophication has been one of the primary environmental problems worrying the coastal countries; it is also the hotspot of marine ecological and environmental research. In this dissertation, the Changjiang estuary and its adjacent coastal waters was chosen as the research object. Based on the data of field surveys during the period of 1997 to 1999 and 2002 to 2003, nutrient distributions, transportation and their limitation for phytoplankton growth in the Changjiang estuary...
