摘要
近年来海洋垃圾污染受到人们的持续关注,为探究威海市海滩垃圾污染状况及主要来源,本文根据威海6条海滩垃圾断面调查资料,掌握了海滩垃圾的种类、丰度和分布特征,并分析了其来源及时空变化.结果表明:2020年威海市海滩垃圾平均数量密度约为15.18万个/km2,平均质量密度约为259.38 kg/km2,其中以塑料类垃圾最多(73.93％)且质量占比最大(59.68％),总体呈数量多、质量轻的特点.在这些海滩垃圾中约79.38％来源于娱乐休闲等人类陆地活动,剩余的20.62％来源于海上渔业养殖等生产活动,通过监管、宣传和回收利用等多种措施减少垃圾的产生.统计表明,威海市海滩垃圾丰度低于我国日照、深圳等海滩垃圾平均水平,亦低于地中海土耳其东部、克罗地亚等世界范围内多个地区的海滩垃圾丰度水平.
