摘要
近年来,草原生态系统发生剧烈变化,灌丛化现象加剧。草原灌丛化的本质是灌木-草本植物相互作用的方向与强度发生改变,从而引起群落结构的变化。本文从灌木-草本植物相互作用的主要影响因素、发生机制及其对群落演替的影响三方面梳理近年研究进展,探讨各种环境因素影响下灌木-草本植物相互作用的变化趋势及其对草原群落的影响,以期为全球气候变化背景下灌木-草本植物动态变化及灌丛化草原群落演替方向预测提供参考,也为我国灌丛化草原的恢复与管理提供理论依据。
In recent years,the grassland ecosystem has undergone drastic changes,and the phenomenon of shrub encroachment has intensified.The essence of shrub encroachment is the change of the direction and intensity of shrub-herb interaction,which leads to the change of community structure.This paper reviews the recent research progress from three aspects:the main influencing factors,the mechanism of shrub-herbaceous interaction and its influence on community succession,and discusses the changing trend of shrub-herb interaction and its influence on grassland community under the influence of various environmental factors.In order to provide reference for the dynamic changes of shrub-herb and the prediction of the direction of shrub encroachment grassland community succession under the background of global climate change.It also provided theoretical basis for the restoration and management of shrub encroachment grassland in China.
