Microplastics pollution have become an environmental issue of global concern due to the extensive use and unreasonable disposal of plastics. The effects of microplastics on terrestrial ecosystems, especially on plant ecosystems, have attracted growing attention. However, the recent researches mainly focus on the individual plants, and study on the plant community-level is still very rare. This review introduces sources of microplastics in plant communities, elaborated the migration and accumulation of microplastics in plant communities, and highlights the effects of microplastics on plant communities, especially on community biomass and community structure. Future research works should further identify the effects of microplastics on different plant communities, especially in areas with higher microplastic pressure such as agricultural fields or around cities, in order to assess the ecological risks of microplastics in the environment more comprehensively.

由于塑料的广泛使用和不合理处置，微塑料污染已成为全球关注的环境问题。微塑料对陆地生态系统，尤其是植物生态系统的影响越来越受到关注。然而，最近的研究主要集中在个体植物上，植物群落层面的研究还非常少见。本综述介绍了植物群落中微塑料的来源，阐述了微塑料在植物群落中的迁移和积累，并重点介绍了微塑料对植物群落的影响，特别是对群落生物量和群落结构的影响。未来的研究工作应进一步确定微塑料对不同植物群落的影响，
