摘要: 土壤微生物是生物地球化学元素循环过程的主要驱动者,对维持陆地生态系统结构和稳定性具有重要作用。尽管已有研究在微生物响应增温的规律与机制方面取得重要进展,但针对微生物响应机制的系统性整合及其性状参数在生态系统模型的科学应用仍显不足。因此,本文聚焦微生物群落结构、生物量、胞外酶活性、呼吸作用及碳利用效率5个核心性状,系统阐述了增温下微生物核心性状的动态变化及响应机制,明确了相关环境变量对其的调控作用。同时,本文概述了目前微生物性状整合入碳循环模型的研究进展,以提升气候变暖下生态系统功能变化的评估精度。基于现有研究进展,本文进一步建议未来研究应着重开展长期定位监测和多生态系统、大尺度的综合研究,以准确预测增温对微生物群落的影响,进而增强微生物驱动生态系统功能的模型预测能力。这将有助于深入解析土壤微生物对气候变暖的响应机制,为生态系统可持续发展提供理论支撑。

Abstract: Soil microorganisms serve as key drivers of biogeochemical cycling processes and are essential for maintaining the structure and stability of terrestrial ecosystems. Although existing studies have made progress in understanding the patterns and mechanisms of microbial responses to warming, there remains insufficient integration of microbial response mechanisms and the scientific application of their trait parameters in ecosystem models. Therefore, this paper focused on five core microbial traits: microbial community structure, biomass, extracellular enzyme activity, respiration, and carbon use efficiency. We systematically expounded the response mechanisms of these core traits driven by warming, clarifying the regulatory effects of relevant environmental variables on them. Meanwhile, this paper outlined current research progress in integrating microbial traits into the carbon cycle models, aiming to enhance the accuracy of assessing changes in ecosystem functioning under climate warming. Based on current research progress, we advocated that future studies should focus on long-term field monitoring and multi-ecosystem, large-scale comprehensive investigation. This would enable accurate prediction of the effects of warming on microbial communities, thereby enhancing model prediction capabilities for microbial-driven ecosystem functions. This will advance mechanistic understanding of soil microbial responses to climate warming and provide theoretical support for sustainable ecosystem management.
