摘　　要：微塑料作为一种新型污染物,不仅存在于陆地环境中,也会通过各种途径进入海洋环境进而散布于海洋的各个角落,对海洋生态系统造成负面影响。因此,研究微塑料在海洋环境中的输运过程,了解其输运的一般规律和影响因素具有现实意义。本文从微塑料入海通量的评估、微塑料输运过程的影响因素以及输运模型优化所涉及的要素方面进行了综述,重点分析了微塑料自身性质及动态变化过程对其输运过程的影响,结果显示微塑料的密度、形状、尺寸以及外部环境因素对其输运过程影响很大。同时在此基础上展望了未来海洋微塑料输运过程数值模拟的研究前景。As a new type of contaminant,microplastics not only exists in the terrestrial environment,but also enters the marine environment through different ways and then spreads in oceans,which has a negative effect on the marine ecosystem.Therefore,it is of practical significance to study the transport process of microplastics in marine environment and to understand the general laws and influencing factors of its transportation.This paper reviewed the evaluation of microplastic transport flux,the influencing factors of microplastic transport process and the factors involved in model optimization.We focused on the effects of microplastic properties and their dynamic processes on the transport process.The results showed that the density,shape,size and external environmental factors of microplastics had great influences on their transport process.This paper proposed three research directions of marine microplastic transport modeling as a prospect of the future study.
