摘 要
海洋塑料污染已成为全球性环境问题，每年约有800万吨塑料垃圾进入海洋，对海洋生态系统、生物多样性及人类健康构成严重威胁。本研究旨在系统分析海洋塑料污染现状，探讨其来源、分布特征及危害机制，并提出针对性治理策略。通过文献综述、实地调查和数据分析相结合的方法，选取典型海域进行样本采集与检测，利用卫星遥感技术和数值模型模拟塑料垃圾的迁移路径，构建了涵盖陆源输入、海流输送等多因素的综合评估体系。研究发现，微塑料污染尤为突出，其在食物链中的累积效应可能影响到顶级消费者的生理机能；同时，塑料碎片成为有害物质的载体，加剧了污染物的扩散风险。基于上述结果，本文创新性地提出了“源头削减-过程阻断-末端治理”的全链条防控模式，强调从政策法规、技术创新和社会参与三个维度协同推进。该研究不仅为理解海洋塑料污染提供了科学依据，也为制定有效的污染防治措施奠定了理论基础，对推动全球海洋环境保护具有重要参考价值。

Abstract
Marine plastic pollution has emerged as a global environmental issue, with approximately 8 million metric tons of plastic waste entering the oceans annually, posing severe threats to marine ecosystems, biodiversity, and human health. This study aims to systematically analyze the current status of marine plastic pollution, investigate its sources, distribution characteristics, and mechanisms of harm, and propose targeted mitigation strategies. By integrating literature review, field surveys, and data analysis, this research collected and tested samples from typical sea areas, utilized satellite remote sensing technology and numerical models to simulate the migration pathways of plastic debris, and established a comprehensive evaluation system incorporating multiple factors such as terrestrial inputs and ocean current transport. The findings revealed that microplastic pollution is particularly prominent, with its accumulation in the food chain potentially affecting the physiological functions of top consumers. Moreover, plastic fragments serve as carriers of harmful substances, exacerbating the risk of pollutant dispersion. Based on these results, this paper innovatively proposes a full-chain prevention and control model of "source reduction-process interception-end-of-pipe treatment," emphasizing coordinated advancement from three dimensions: policy and regulation, technological innovation, and social participation. This research not only provides scientific evidence for understanding marine plastic pollution but also lays a theoretical foundation for formulating effective pollution prevention measures, offering significant reference value for promoting global marine environmental protection.
