Key Points

This research aims to analyze the characteristics and risk levels of beach litter pollution in a coastal tourism area.
Conducted an analysis of beach litter density and types in Qinzhou, Guangxi.
Utilized the Clean-Coast Index (CCI) and Hazardous Anthropogenic Beach Litter Index (HABLI) for assessment.
Evaluated spatial distribution of litter based on different coastal activities and seasons.
Beach litter density was found to be 53.11±20.72 million items/km² and 3553.01±2698.06 kg/km².
Litter density was higher on corners compared to straight beaches, and shipping areas had more litter than tourism zones.
Summer and autumn showed higher litter density compared to winter and spring.
Plastic waste constituted 71.02% of beach litter, primarily from human coastal activities (37.5%).
The CCI level was rated as unclean (CCI = 10.40), while the HABLI level indicated moderate safety (HABLI = 0.23).

Abstract

在广西钦州市三娘湾旅游度假区海滩垃圾的密度、材料类型、来源类型和尺寸类型及其空间分布调查分析基础上，利用清洁海岸指数（clean-coast index, CCI）和海滩垃圾危害人体健康指数（hazardous anthropogenic beach litter index, HABLI）评估海滩垃圾污染等级。三娘湾旅游度假区海滩垃圾数量密度和质量密度分别为（53.11±20.72）万个/km2和（3553.01±2698.06）kg/km2。岬角侧滩的海滩垃圾数量密度和质量密度均高于平直海滩，航运活动区高于旅游活动区；夏、秋季海滩垃圾的数量密度高于冬、春季。海滩垃圾的材料类型以塑料类垃圾占比（71.02%）最高，来源类型以人类海岸活动占比（37.5%）最高，尺寸类型以中块垃圾占比（61.56%）最高。三娘湾旅游度假区CCI等级为不清洁（CCI =10.40），HABLI等级为适度安全（HABLI=0.23）。
