土壤碳库是陆地生态系统中最大的碳库,约占陆地生态系统总碳库的2/3,其碳循环过程在调节全球碳平衡和缓解气候变暖等方面具有重要的作用.目前,对森林土壤有机碳的研究已取得了很多重要的进展.本文阐述了森林土壤有机碳的形成过程、空间分布特征、估算方法及评价,重点阐明了森林土壤有机碳动态的影响因素,剖析了森林土壤有机碳动态研究过程中存在的问题和今后的研究重点,以期为进一步了解土壤有机碳的时空动态变化提供参考.
Research Progress on the Forest Soil Organic Carbon Dynamics
As the largest carbon pool in the terrestrial ecosystem,the soil carbon pool accounts for about 2/3 of the total carbon pool in the terrestrial ecosystems,and its carbon cycling process plays an important role in such aspects as regulating the global carbon bal-ance and mitigating climate warming.Up to now,many important advances have been made in study on the forest soil organic carbon.In this paper,an elaboration was made on the formation process,spatial distribution characteristics and estimation methods and analy-sis of the forest soil organic carbon with a focused generation of the influencing factors of the forest soil organic carbon dynamics and an analysis on the existing problems and future priorities in studying the forest soil organic carbon dynamics,so as to provide reference for further understanding the spatial-temporal dynamics of the soil organic carbon.
