Abstract
Soil microorganisms, by actively participating in the decomposition and transformation of organic matter through diverse metabolic pathways, play a pivotal role in carbon cycling within soil systems and contribute to the stabilization of organic carbon, thereby influencing soil carbon storage and turnover. Investigating the processes, mechanisms, and driving factors of soil microbial carbon cycling is crucial for understanding the functionality of terrestrial carbon sinks and effectively addressing climate change. This review comprehensively discusses the role of soil microorganisms in soil carbon cycling from three perspectives: metabolic pathways, microbial communities, and environmental influences. It elucidates the roles of different microbial species in carbon cycling and highlights the impact of microbial interactions and environmental factors on carbon cycling. Through the synthesis of 2171 relevant papers in the Web of Science Core database, we elucidated the ecological community structure, activity, and assembly mechanisms of soil microorganisms crucial to the soil carbon cycle that have been widely analyzed. The integration of soil microbial carbon cycle and its driving factors are vital for accurately predicting and modeling biogeochemical cycles and effectively addressing the challenges posed by global climate change. Such integration is vital for accurately predicting and modeling biogeochemical cycles and effectively addressing the challenges posed by global climate change.
土壤微生物通过多种代谢途径积极参与有机质的分解转化,在土壤系统内的碳循环中起着关键作用,有助于有机碳的稳定,从而影响土壤碳储量和周转。研究土壤微生物碳循环的过程、机制和驱动因素对于理解陆地碳汇的功能和有效应对气候变化至关重要。本文从代谢途径、微生物群落和环境影响三个方面综述了土壤微生物在土壤碳循环中的作用。阐明了不同微生物种类在碳循环中的作用,强调了微生物相互作用和环境因素对碳循环的影响。通过对Web of Science Core数据库中2171篇相关论文的综合整理,阐明了对土壤碳循环至关重要的土壤微生物的生态群落结构、活性和组装机制。土壤微生物碳循环及其驱动因子的整合对于准确预测和模拟生物地球化学循环,有效应对全球气候变化带来的挑战至关重要。这种整合对于准确预测和模拟生物地球化学循环以及有效应对全球气候变化带来的挑战至关重要。
期刊介绍:
The Science of the Total Environment is an international journal dedicated to scientific research on the environment and its interaction with humanity. It covers a wide range of disciplines and seeks to publish innovative, hypothesis-driven, and impactful research that explores the entire environment, including the atmosphere, lithosphere, hydrosphere, biosphere, and anthroposphere.
The journal's updated Aims & Scope emphasizes the importance of interdisciplinary environmental research with broad impact. Priority is given to studies that advance fundamental understanding and explore the interconnectedness of multiple environmental spheres. Field studies are preferred, while laboratory experiments must demonstrate significant methodological advancements or mechanistic insights with direct relevance to the environment.
