中文摘要：

土壤有机碳是土壤碳库的重要成分,在碳循环中起重要作用。本文主要从不同陆地生态系统的角度阐述了影响土壤有机碳的自然因素和人为因素、研究方法以及空间分布的研究进展,为陆地生态系统的可持续发展提供理论依据,也为全球碳循环的研究提供依据。

英文摘要：

Soil organic carbon,important component of soil carbon pool,plays an important role in global carbon cycle.In this paper,from the perspective of different terrestrial ecosystems,the natural and man-made factors affecting soil organic carbon,research methods and research progress of spatial distribution were described.That provided a theoretical basis for the sustainable development of terrestrial ecosystems and the global carbon cycle of terrestrial ecosystems.
