摘　　要：2019年秋季,对天津近岸海域海洋垃圾的分布特征进行了调查研究。结果表明:海面漂浮的大块和特大块垃圾平均密度为7.7个/km^(2),主要材质为塑料类(84.6%);表层海水中中小块垃圾的平均分布密度为626.8个/km^(2),主要材质为塑料类(63.6%);海滩垃圾平均分布密度为423.6个/km^(2),主要材质为塑料类(52.5%)。通过样品类型判断,天津近岸海域海洋垃圾可能主要来源于陆上。The distribution characteristics of marine debris in Tianjin coastal waters were researched in autumn of 2019. The results show that the average density of large and super large debris floating on the sea was 7.7 pieces/km^(2),and the composition was mainly plastics(84.6%). The average density of small and medium-sized debris floating on the sea was 626.8 pieces/km^(2),and the composition was mainly plastics(63.6%). The average density of debris in beach was 423.6 pieces/km^(2),and the composition was mainly plastics(52.5%). According to the sample types, the marine debris in Tianjin coastal waters might mainly come from land.
