摘要:

在全球气候变化背景下,植物入侵现象日益加剧,入侵植物通过降低本地生物多样性,改变土壤微生物群落结构与组成,影响生态系统结构与功能,显著改变土壤氮循环等生态过程。土壤氮循环是生态系统物质循环的重要环节,影响生态系统中氮供应与分配,而全球气候变化和植物入侵正在改变土壤氮循环的效率和途径。菌根作为真菌和植物根系的重要共生体,在土壤氮循环过程中起着至关重要的作用。目前,对于菌根真菌与入侵植物互作对土壤氮循环的影响,仍缺乏系统研究和深入理解。该文综述了近年来关于入侵植物与菌根真菌互作对土壤氮循环影响的相关研究进展,重点分析了入侵植物与菌根真菌互作通过调控土壤微生物群落,影响土壤硝化、反硝化作用及相关土壤酶活性,改变土壤理化性质等机制影响土壤氮循环,并对未来研究方向提出展望。该研究为理解入侵植物在全球土壤氮循环中的作用提供新的视角,并为入侵植物管理与植物入侵影响下氮循环响应评估提供理论依据。

Abstract:

In the context of global climate change, the phenomenon of plant invasion has been increasingly intensified. Invasive plants affect biodiversity by reducing local species, altering soil microbial community structure and composition, and impacting ecosystem structure and function, which significantly modifies ecological processes such as soil nitrogen cycling. Soil nitrogen cycling is a crucial component of ecosystem nutrient cycling, influencing nitrogen supply and distribution within ecosystems. Both global climate change and plant invasion are altering the efficiency and pathways of soil nitrogen cycling. Mycorrhizae, as an important symbiotic association between fungi and plant roots, play a vital role in the soil nitrogen cycle. However, there is still a lack of systematic research and in-depth understanding of the impact of mycorrhizal interactions with invasive plants on soil nitrogen cycling. This review summarized recent progress in research on the interaction between invasive plants and mycorrhizal fungi in the context of soil nitrogen cycling, focusing on mechanisms such as the regulation of soil microbial communities, the effects on soil nitrification, denitrification, and related soil enzyme activities, and alterations in soil physicochemical properties that influence soil nitrogen cycling. Additionally, the paper proposed future research directions. This study provided new perspectives for understanding the role of invasive plants in global soil nitrogen cycling and offered theoretical support for invasive plant management and nitrogen cycling response evaluation as affected by plant invasions.
