Study of different disturbances impact on grassland carbon cycle

Grassland carbon cycle is related to the grassland vegetation,climate and soil conditions as well as all kind of interferences.In recent decades,human interference activities have had a great impact on grassland carbon cycle.This paper introduces the current research and its progress of the impact on grassland ecosystem carbon cycle caused by grazing utilization,management measures as well as climate change,also points out that future studies on carbon cycle in grassland should focus on different disturbances impact on grassland ecosystem carbon cycle,modeling carbon dynamics in grassland ecosystem associated with disturbances and the mechanisms of disturbances on grassland ecosystem carbon cycle.
