本文根据１９９２～１９９３年的４个季节观测资料，对厦门西海域水体富营养化与赤潮关系进行了研究，结果表明同安湾、厦门西港、九龙江口均属于中营养海区，马銮湾、筼筜湖均属于过营养海区。同安湾、厦门西港、九龙江口浮游植物数量少，种类多，马銮湾、筼筜湖则相反。马銮湾扭曲小环藻、柔弱菱形藻形成了慢性赤潮。筼筜湖扭曲小环藻、骨条藻已形成了赤潮。马銮湾生态养殖，筼筜湖污水治理后，水质明显地得到改善，同时也减轻了厦门西港环境容量的负荷，１９８８年以来，厦门西港未再发生赤潮。
Based on the four seasons observation data from 1992 to 1993, the relationship between eutrophication and red tide in the west of Xiamen was studied. The results show that Tong’an Bay, Xigang, Xiamen and Jiulongjiang estuary all belong to the middle nutrient zone, Maluan Bay, Lakes belong to over-nourished sea area. Tong’an Bay, Xiamen West Port, Jiulongjiangkou a small number of phytoplankton species more, Maluan Bay, Lake Qionglai is the opposite. Maluan Bay distorts the Cyclotella, the weak Rhodophyta formed a chronic red tide. Xuyi Lake twisted Cyclotella, Skeletonema algae has formed a red tide. Maluan Bay ecological culture, Lake Qionglai sewage treatment, water quality has been significantly improved, but also reduce the load of the Xiamen Western Harbor environmental capacity, since 1988, no recurrence of red tide Xiamen Western Harbor.
