摘　　要：微塑料(<5 mm)是一种新兴污染物,由于其具有迁移、转化、吸附和降解等特性,对生态环境和人类健康构成严重危害和潜在风险。氮循环在生物地球化学循环中起决定性作用,其关键过程主要由微生物驱动,而微塑料进入环境后通过影响微生物的种群、丰度和类型进而影响氮循环。为保护土壤生态环境,降低塑料对农业生产的危害提供参考,综述土壤微塑料来源和微塑料对土壤酶活性、微生物、氮循环及其相关基因的影响等方面的研究进展,并从扩大微塑料类型、粒径和开展浓度及土壤-微生物-植物多因素耦合长期野外试验等方面展望其研究方向。Microplastics(<5 mm)is an emerging contaminants.Due to its migration,transformation,adsorption and degradation properties,microplastics poses a serious harm and potential risks to the ecological environment and human health.Nitrogen cycling plays a decisive role in biogeochemistry cycling,and its key process is mainly driven by microorganisms,and the existence of microplastics can influence the nitrogen cycling through affecting microbial population,abundance and type.In order of provide the reference for protecting the ecological environment of soil,reducing the harm of microplastics to agricultural production,the research progress on soil microplastics source and the effects of microplastics on soil enzyme activity,microorganism,nitrogen cycling and its related genes are reviewed.At the same time,the research directions of expanding microplastics types and particle size,and conducting concentration and longterm field experiments on multi-factor coupling of soil-microbial-plant are prospected.
