Abstract

Red tide researches in China were reviewed. It is divided into three stages: (1)Preliminary stage, (2) Opening stage and (3) developing stage. The research of red tide is uprisingly developed in this past decade, especially the two major projects dealing with HAB, supported by NSF, China, greatly promoted the progress of red tide research. It, of course, is fairly linked with international cooperation.

Red tide occurrence dramatically increased recently in China. Their tendency is discussed. It assumed that: (1) causative species diverted, also the dominant taxa from diatoms insteaded by dinoflagellates; (2) initiation frequency increased; (3) cover area expanded; (4) lasting period expanded and (5) toxic species and toxic impact grew.

The research of red tide in China linked with GEOHAB program is expected vigorously development as the new national HAB program (973) starts. It gives the research a new energy.
