摘　　要：外来入侵植物不仅影响植物群落组成、生物多样性以及生态系统的结构和功能,而且显著影响土壤氮(N)的转化过程。外来入侵植物对N循环影响的研究已成为入侵生态学的研究热点。N循环与凋落物的分解和养分释放有关,外来入侵植物能够改变凋落物的组成与结构,进而影响土壤的N转化过程。另外,外来入侵植物的化感作用也会影响土壤N转化过程,这些作用与土壤微生物的结构与功能变化密不可分。该文主要从凋落物分解与养分释放及外来入侵植物化感作用两个方面综述了外来入侵植物对土壤N转化的影响,总结了外来入侵植物对土壤N转化相关土壤微生物(尤其是氨氧化细菌与氨氧化古菌)的影响,探讨了土壤N转化对外来植物入侵的反馈,并探讨了丛植菌根真菌与外来入侵植物的互相影响。Invasive alien plants not only influence plant community composition,biodiversity and ecosystem structure and function,but also have severe impacts on soil nitrogen transformation processes.The effects of invasive alien plants on nitrogen(N)cycling have been one of the hot topics in invasion ecology.Litter decomposition and its nutrient release play an important role in nutrient cycling.In addition,invasive alien plants have the potential to influence soil N transformation through allelopathy.All these processes are tightly related to soil microbes.Therefore,this review mainly focuses on litter decomposition and its nutrient release,and allelopathy to understand the effects of plant invasion on soil N transformation.Changes in soil N transformation and soil microbes(esp.Ammonia oxidizing bacteria and Ammonia oxidizing archaea)due to plant invasion,as well as the feedbacks of these changes to further invasion of alien plants were discussed.Finally,the interactions between arbuscular mycorrhizal fungi and plant invasion were reviewed.
