摘要：
HAB (harmful algal bloom) is a serious marine ecological disaster. Up to now there is no definite conclusion about its mechanism of occurrence. The observation results show that the HAB breakout in the Xiangshan Bay was mainly caused by physical convergence capacity,and the breakout process had no direct relation to eutrophication. As a new idea it is thought that the process of the HAB breakout is mainly a physical convergence or accumulation process in some areas. A hypothesis about dynamic mechanism of the HAB appearing in the area off the Changjiang Estuary is put forward according to hydrology and topography and the past work, and a breakthrough is expected to be made for doing further research.
