Abstract

The marine environmental condition is extremely important to maintain the sustainable propagation and compensation of the biological communities and keep the ecological balance in Changjiang estuary. The Changjiang estuary is a sensitive zone of HAB as a most serious eutrophic sea area in China influenced by the massive nutrient load of Changjiang and other coastal drain contamination. Based on the recent various monitor material about the hydrometeorology, chemical, sediment and biological communities in Changjiang estuary, this article analyze the marine environmental condition by the numbers and discuss the characteristics of the HAB in Changjiang estuary.
