杉木人工林土壤有机碳和微生物特征及其影响因素的研究进展

土壤有机碳作为土壤碳库的重要组成部分，其稳定、增长或衰减都与大气二氧化碳变化密切相关。土壤微生物作为森林生态系统不可或缺的一部分，参与了有机物分解和土壤物质转化过程，在维持土壤质量中起着重要作用。近年来对杉木Cunninghamia lanceolata林土壤的研究主要集中在杉木凋落物分解、土壤养分周转、土壤微生物特征等方面，尤其是高通量测序技术的广泛应用，使杉木林土壤有机碳和微生物特征的研究取得了较多重要进展。本研究对杉木林土壤有机碳的碳库特征、活性、稳定性和土壤微生物的群落结构与多样性及其影响因素的研究进展进行了综述，并提出了未来杉木林土壤有机碳与土壤微生物的研究方向。参79

Research progress on soil organic carbon and microbial characteristics of Cunninghamia lanceolata plantation and their influencing factors

As an important part of soil carbon pool, the stability, growth or attenuation of soil organic carbon are closely related to the change of atmospheric CO₂ concentration. Soil microorganisms, an indispensable part of forest ecosystem, participate in the decomposition of organic matter and the transformation of soil matter and play an important role in maintaining soil quality. The relationship between soil organic carbon and microbial characteristics is extremely close. In recent years, the research on soil in Cunninghamia lanceolata plantation in China has mainly focused on litter decomposition, soil nutrient turnover, soil microbial characteristics and so on. With the wide application of high-throughput sequencing technology, the research on soil organic carbon and microbial characteristics of C. lanceolata plantation has made a lot of important progress. In this study, the research progress on pool characteristics, activity, and stability of soil organic carbon as well as community structure and diversity of soil microorganisms and their influencing factors in C. lanceolata plantation were reviewed, and the future research direction of soil organic carbon and soil microorganism in C. lanceolata plantation was put forward.
