| 中文摘要: |
| 2020—2022年在浙江省温岭市近岸海域布设监测断面，采集海洋垃圾，分析其分布和组成特征，解析其来源，并使用清洁海岸指数（CCI）及危险物品指数（HII）对海滩垃圾质量进行评估。结果表明：温岭市近岸海域海面漂浮大块及特大块垃圾年平均数量密度为37.7个/km2；海面漂浮小块及中块垃圾年平均数量密度为3 568.2个/km2；海滩垃圾数量密度为5 813.5个/km2。海洋垃圾主要材料类型为塑料类和聚苯乙烯泡沫塑料类，其主要来源于陆地人类生产活动。近岸海域CCI和HII指数年均值分别为0.11和0.66，表明温岭市洞下沙滩处于非常清洁且安全水平。 |

| The monitoring sections were set up in the coastal waters of Wenling， Zhejiang from 2020 to 2022， to collect marine debris， analyze its distribution and composition characteristics and sources， and evaluate the beach environmental quality with Clean Coast Index（CCI） and Hazardous Items Index（HII）. The results revealed that in the coastal area of Wenling， the average annual density of large and extra large pieces of floating garbage was 37.7 items/km2. The average annual density of small and medium sized floating garbage was 35682 items/km2. The density of beach litter was 5 813.5 items/km2. Plastics and polystyrene foam plastics were dominant， which mainly came from human activities. The annual average CCI and HII in the coastal waters were 0.11 and 0.66， respectively， indicating that Dongxia Beach in Wenling was at a very clean and safe level. |
