摘　　要：总结归纳了30多年来秦皇岛海域赤潮事件特征,分析该海域赤潮成因并提出防治对策及建议。1990—2023年,秦皇岛海域共记载赤潮事件79次;赤潮发生时间集中在5月—8月,6月最多;共涉及赤潮生物33种,引发赤潮次数较多的生物有夜光藻、锥状斯克里普藻、抑食金球藻、红色中缢虫、微小原甲藻等;有毒赤潮发生频次及占比整体呈增加态势;赤潮发生热点区域为入海河口、浴场、秦皇岛港等营养盐丰富或水体交换能力较差的区域。秦皇岛海域赤潮防治提出了严格控制陆源污染物入海量、强化港口码头污染防治及大力推进赤潮监测预警能力建设等对策。This research summarized the characteristics of red tide in Qinhuangdao sea area in recent 30 years,analyzed the causes and proposed countermeasures and suggestions.From 1990 to 2023,79 red tide events were recorded in Qinhuangdao sea area.The occurrence time of red tide was concentrated in may to August,and the most occured in June.A total of 33 species of red tide organisms were involved,and the organisms that caused red tide more frequently were noctiluca scintillans,scrippsiella trochoidea,aureococcus anophagefferens,mesodinium rubrum,prorocentrum minimum.The frequency and proportion of toxic red tide increased gradually.The hotspots of red tide occurred in the areas with abundant nutrients or poor water exchange capacity,such as estuaries,bathing beachs,and Qinhuangdao Port.The countermeasures of red tide prevention and control include strictly control the inflow of land-based pollutants,strengthen pollution prevention and control of port and dock,vigorously promote the construction of red tide monitoring and early warning capacity.
