Based on the relevant red tide data and research works, the distribution of coastal waters where red tides frequently occurred, main species of red tide organism, environmental conditions and red tide ecological characteristics in Chinese coastal waters were analyzed. The results showed that the Liaodong Bay, Bohai Bay, Laizhou Bay, Dalian Bay, the Changjiang River estuary, waters around Zhoushan Islands, Hangzhou Bay, Xiamen Bay, Zhelin Bay, Dapeng Bay and the Pearl River estuary were the frequent occurrence areas of red tide. Many factors might influence the occurrence of red tide, which included weather, hydrodynamic and nutrient conditions, and the variation of biological environment. Human activity, such as marine aquaculture and pollution discharged from land which accelerated eutrophication in coastal waters was also an important impact factor on red tide. However, eutrophication is not the only key to red tides, red tides also occurred in sea area with low nutrient concentration. Long-term spot monitoring should be strengthened and deeper research work should be developed, aiming at the mechanism and key inspiring factors of red tides.
