Affecting Factors of Soil Organic Matter Carbon and Its Determination Ways

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.
