摘要

摘要: 森林土壤有機碳庫（SOC）是全球碳循環和陸地生態系統重要組成部分，對氣候變化有重要影響。幾乎所有的森林樹木根系都與叢枝菌根（AM）或外生菌根（ECM）真菌共生，但2種菌根樹種的土壤碳循環存在差異。本文綜述了目前研究中2種菌根樹種土壤SOC儲量存在差異的原因，總結了調控不同菌根樹種SOC分解的機制以及可能在區域尺度上的變異，展望了未來菌根樹種SOC研究方向和熱點，旨在為精準預測菌根真菌對森林土壤碳匯的影響提供參考。

Abstract: Forest soil organic carbon (SOC) pool is a key component in global carbon cycles and terrestrial ecosystems, which plays a vital role on climate change. Nearly all tree species develop symbiotic relationships with either arbuscular mycorrhizal (AM) or ectomycorrhizal (ECM) fungi to acquire nutrients from soils, but there were differences in soil carbon cycling between the two mycorrhizal species. This paper reviewed the reasons for the differences in SOC stock between the two mycorrhizal tree species, summarized the mechanism of regulating SOC decomposition of different mycorrhizal tree species and their possible variations at the regional scale, and looked forward to the future research direction and hotspots of mycorrhizal tree SOC, aiming to provide a helpful reference for accurately predicting the impact of mycorrhizal fungi on forest soil carbon sinks.
