摘　　要：近年来微塑料污染给全球生态环境带来的危害与威胁已不容忽视,由于水环境与水动力条件改变,大量微塑料随水流迁移至河口会与细颗粒泥沙相遇碰撞而发生异质聚集,显著改变各自输移行为,进而影响颗粒物的归趋,并对环境中其他要素产生影响。为进一步梳理并明晰泥沙与微塑料异质聚集的驱动因素、聚集输移特征与机理及其环境效应,本文结合近年国内外研究动态,探讨并总结河口细颗粒泥沙与微塑料异质聚集的驱动因素及其环境效应,充实了泥沙及其聚集物的环境效应理论,拓展延伸理论研究维度,从宏观、介观、微观层面提出了异质聚集环境效应的评估指标体系。本研究有助于丰富与深化环境泥沙及其环境效应的理论体系,可为强化河口水环境治理技术、提升水污染防控水平和能力提供理论支撑。In recent years,the harm and threat of microplastics pollution to the global ecological environment cannot be ignored.Due to changes in water environment and hydrodynamic conditions,a large number of microplastics will migrate to estuaries with water flow and collide with fine particles and sediment,resulting in heterogeneous aggregation and changing their transport behavior significantly,thus affecting the trend of particulate matter and other elements in the environment.In order to further clarify the driving factors,aggregation and transport characteristics,mechanism and environmental effects of sediment and microplastics heterogeneous aggregation,this paper combined with recent domestic and foreign research developments,discussed and summarized the driving factors and environmental effects of fine particles sediment and microplastics heterogeneous aggregation in estuaries,enriched the environmental effects theory of sediment and its aggregates,and extended the theoretical research dimension.An evaluation index system for the environmental effects of heterogeneous aggregation is proposed from the macro,mesoscopic and micro levels.This study is helpful to enrich and deepen the theoretical system of environmental sediment and its environmental effects,and can provide theoretical support for strengthening estuarine water environmental management technology and improving the level and ability of water pollution prevention and control.
