摘　　要：菌根作为由菌根真菌与植物根系组成的共生体,影响植物-土壤系统水分吸收、养分运输等过程,进而影响植被生长。伴随着全球环境变化,植被生长面临着多重胁迫。在此背景下,系统理解变化环境下菌根对植被生长的调控过程和机理具有重要意义。本文梳理了多变环境下菌根和植被相互作用的相关研究进展,重点阐述了养分亏缺、干旱胁迫、盐胁迫及重金属胁迫等条件下菌根与植被生长的关系,并对变化环境下菌根作用于植物生长的机制和模式进行了简要概括,最后总结了当前研究中存在的主要问题,指出在全球环境变化的背景下,系统深入研究菌根生态学,揭示菌根在植物生长和植被恢复中的作用及机理,对我国可持续生态恢复和建设具有重要意义。As an important symbiont composed of mycorrhizal fungi and plant roots,mycorrhizas affect water absorption and nutrient transportation in the plant-soil system,with consequence on vegetation growth.Under global environmental change,vegetation growth is suffered from multiple stresses.It is of great significance to systematically understand the underlying processes and mechanisms for the effects of mycorrhiza on vegetation growth in a changing environment.We summarized the research progress on the interactions between mycorrhiza and vegetation growth under changing environment,particularly emphasizing on the relationships between mycorrhiza and vegetation growth under nutrient limitation,drought stress,salt stress,and heavy metal stress.Then,we briefly summarized the mechanisms and modes underlying the effects of mycorrhiza on vegetation growth under changing environment.Finally,we summarized the key knowledge gaps in the current research.We propose that it is crucial to systematically study the mycorrhizal ecology and uncover the mechanisms underlying the mycorrhiza effects on plant growth and vegetation restoration,which is important for sustainable ecological restoration and construction under the background of rapid global environmental changes.
