a 1995～2004,the discussion on the reasons and mechanism of red tide formed was done.

Research advancement on controlling red tide by natural clay;

Preliminary Study on using MODIS to detect the Red Tide in the Yangtze Estuary and adjacent waters;

Influencing analysis of human activities on frequency of red tides(HABs) in Zhejiang Sea Areas;

Studies on PSP in harmful red tides of Zhejiang Sea-areas;

Characteristics of ecological environment and monitoring of red tides in the waters of Qinhuangdao;

Survey and adapted hydro-meteorological conditions of Noctiluca Scintillans red tides in South China Sea;

Spatial and temporal distribution of the nutrients and its controlling factors in the high-frequency HAB occurrence area in the East China Sea;

The HAB Species Prorocentrum dentatum and its Characteristics in East China Sea;

Numerical simulation of the dynamic mechanism of the occurrence and spread of HAB;

Observation of harmful algal blooms caused by Prorocentrum and Gymnodinium species in the western Xiamen Harbour;

Relationship between harmful algal bloom and transport of iron in atmospheric dust;

Based on the data from four cruises that carried out in the Changjiang River estuary and its adjacent areas from 2002-04 to 2003-02,the seasonal variation and spatial distribution of nutrients were analyzed,and the relationship between nutrients condition and the harmful algal blooms(HABs) was also discussed.
