摘要/Abstract

摘要： 由于自然因素或人类因素驱动，以CO₂浓度增加、气候变暖、大气氮沉降等为主要特征的生态效应对草地生态系统产生了复杂的影响。草丛-地境界面中草地植被和土壤环境对全球变化的响应十分敏感，土壤微生物与草地植被和土壤环境之间的关系密切，不同层面上微生物对全球变化的响应特征不同。气候变化的各个因素对土壤微生物有直接或间接的作用，且目前作用机制尚不明确。本文综述了全球变化因子，包括CO₂浓度、气温及氮沉降等因素对草地土壤微生物影响的相关研究进展，在此基础上分析评述了全球变化对草地生态系统微生物多样性的影响及微生物的响应机制，并对未来研究需关注的问题和方向进行了探讨和展望。

关键词: 全球变化, 草地生态系统, 微生物群落多样性, 草丛-地境界面

Abstract: The effects of global changes on grassland ecosystems have become a focus of great concern in the whole world due to natural factors and human activities. The ecological effects of global changes, including elevated CO₂, warming, and increased nitrogen deposition, on grassland ecosystems are complex. The responses of the grassland vegetation and soil environment of plant-site interface to global changes are very sensitive, and there is a close relationship between soil microbial communities and the plant-site interface of grassland ecosystem. The response mechanisms of microorganisms to global changes differ from different levels. The factors of climate changes have direct or indirect effects on soil microorganisms, but the mechanisms are still not clear. The effects of global changes, including elevated CO₂, warming, and increased nitrogen deposition, on the soil microbial community diversities of grassland ecosystems and the response mechanisms of grassland microorganisms to global changes are reviewed in this paper. And the issues and research trends are discussed.

Key words: Global changes, Grassland ecosystems, Microbial community diversity, Plant-site interface
