摘　　要：草地碳循环不仅与草地植被、气候和土壤状况有关,而且与各类干扰利用活动密切相关,特别近几十年,人类的利用干扰活动对草地碳循环产生了巨大的影响。本文综合介绍了放牧利用、管理措施以及气候变化等干扰对草地生态系统碳循环影响方面的研究现状和进展,同时提出未来草地生态系统碳循环主要的研究方向,即不同干扰互交对草地生态系统的影响、模型方法在干扰与草地生态系统碳循环研究中的应用、干扰对草地碳循环影响的驱动机理。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.
