Abstract

Abstract:

Thermal adaptability of soil microbial respiration is considered to be an important mechanism that determines the feedback effects of terrestrial ecosystem on global warming. It may significantly change the trend of climate change in the future. However, little is known about how the soil microbial community structure change causes the thermal adaptability of soil microbial respiration. More research is needed to accurately assess the influence of thermal adaptability of soil microbial respiration in order to predict the future trend of climate change. This paper addressed the current controversies and debates on the thermal adaptability of soil microbial respiration and microbial diversity based on the research on the impact of global climate change on soil microbial respiration. The paper also proposed a conceptual model for studying soil microbial community structure and diversity under global climate change by comparing three fundamental theories of microbial community construction and an ecological metabolism theory. At present, several views have been accepted, such as conducting long-term positioning monitoring studies in natural ecosystems to verify the thermal adaptability of soil microbial respiration, constructing local scale sequences of climate cooling and warming, revealing the response mechanism of soil microbial community succession and functional genome to climate conditions, and answering whether climate warming and cooling have significantly changed the soil microbial community structure as well as predicting the future trend of climate change. These ideas are helpful for revealing the micro-mechanism and driving mechanism of soil microbial in response to climate change.

Key words: global climate change, soil microbial respiration, thermal adaptability, microbial community structure, microbial diversity, response

摘要：

土壤微生物呼吸热适应性被认为是决定陆地生态系统对全球变暖反馈作用的潜在重要机制,可能显著改变未来的气候变化趋势,然而,土壤微生物群落结构变化如何引起土壤微生物呼吸热适应性的研究目前尚存争议。该文针对气候变化对土壤微生物呼吸的影响研究,梳理了当前对土壤微生物呼吸的热适应性是否存在的争议和不同观点与结论,综述了气候变化对土壤微生物群落结构及多样性的影响研究与最新进展。通过比较当前微生物群落构建的三大理论基础与生态代谢理论,构建了全球气候变化问题下土壤微生物群落结构和多样性研究概念模型。总体而言,目前比较认同的几个观点是,在成熟的自然生态系统中进行长期定位监测研究,验证土壤微生物呼吸的热适应性问题;通过构建气候变冷和变暖的局域尺度序列,利用宏基因组研究技术,回答气候变暖和气候变冷是否显著改变了土壤微生物群落结构;运用生态代谢理论研究气候变化背景下土壤微生物呼吸特征及微生物多样性变化规律,建立功能基因与土壤微生物呼吸强度的定量关系,揭示土壤微生物群落演替及功能基因组对气候条件变化的响应机理,进而预测未来的气候变化趋势。这些思路有助于深入揭示土壤微生物对气候变化响应的微观机理和驱动机制。
