英文摘要：

This paper summarizes the definition of allelopathy,including the categories,functions and mechanisms of allelochemicals in red tide succession, as well as the allelopathic growth inhibition of phytoplankton by different aquatic plants,microalgae and microbes.Considering that allelopathy is one of the mechanisms thought to control red tides,the authors emphasize that future research should mainly focus on the isolation and identification of new allelochemicals and the mechanisms of allelopathy. Intensive study of allelopathy should provide new red tide control methods.
