植物-土壤微生物反馈在草地演替过程中的作用机制

The Mechanism of Plants-Soil Microbial Feedback in Grassland Succession

植物-土壤反馈影响生态系统结构、功能及过程,推动植物群落组成的变化,对解释植物群落的演替进程和方向、维持植物群落多样性和稳定性有着重要意义,已成为近年生物学和生态学研究热点。植物-土壤微生物反馈是植物-土壤反馈的重要组成部分。重点综述植物-土壤微生物反馈在植物群落演替过程中的作用机制,简要指出目前研究中存在的不足,并对未来研究中值得重点关注的科学问题进行了探讨与展望。

Plant-soil feedback affects the structure,function and process of ecosystems,and promotes the dynamic changes of plant community composition,which is of great significance to explain the succession process and direction of plant communities and maintain the diversity and stability of plant community.In recent years,the study of plant-soil feedback in community succession has become a hotspot in biological and ecological,but the current research results are inconsistent,and its mechanism of action is not clear.Plant-soil microbial feedback is an important part of plant-soil feedback.Based on the extensive review of the existing research results,the study focuses on the mechanism of plant-soil microbial feedback in the succession of plant communities,and points out some of the deficiencies in the current research,and discussed and prospected the scientific issues worthy of special attention in future research.
