摘　　要：基于2022年河北省沿海三市近岸海域海洋垃圾统计数据,分析了秦皇岛市、唐山市、沧州市近岸海域海面漂浮垃圾和海滩垃圾的数量、组成及来源。结果表明,2022年仅沧州海域出现海面漂浮大块和特大块垃圾,平均个数为274个/km^(2),秦皇岛、唐山和沧州海面漂浮中块和小块垃圾平均个数分别为810、2 250、358个/km^(2),平均密度分别为0.02、0.31、0.62 kg/km^(2)。沿海三市海滩垃圾平均个数分别为2 005 297、2 435 500、11 000个/km^(2),平均密度分别为266.25、1 071.89、343.20 kg/km^(2)。海面漂浮垃圾和海滩垃圾基本均以塑料类为主,人类海岸活动是海洋垃圾的主要来源。Based on the statistical data of marine litter in the three coastal cities in Hebei Province in 2022,the quantity,composition and source of floating and beach marine litter in the coastal waters of Qinhuangdao,Tangshan and Cangzhou are analyzed.The results show that in 2022,the large and out sized floating marine litter are only observed in Cangzhou with an average number of 274 pcs/km^(2).For the middle and small sized floating marine litter,their average number in Qinhuangdao,Tangshan and Cangzhou are 810,2 250 and 358 pcs/km^(2),respectively,and their average density are 0.02,0.31 and 0.62 kg/km^(2),respectively.The average number of beach marine litter in three coastal cities are 2 005 297,2 435 500 and 11 000 pcs/km^(2),respectively,with an average density of 266.25,1 071.89 and 343.20 kg/km^(2),respectively.The floating and beach marine litter are generally composed of plastics,and mainly originated from human coastal activities.It is suggested that the ecological environment department should improve the marine litter monitoring and law enforcement supervision,and effectively reduce the discharge of marine litter.
