In the context of "Carbon Emissions Peak" and Neutrality", grazing exclusion (GE) has been applied widely to rehabilitate degraded grasslands increase carbon sequestration. However, on QingZang Plateau (QZP), impacts GE dynamics alpine are poorly understood, particularly at a regional scale. To fill this knowledge gap, we evaluated responses sequestration in different across QZP by using meta-analysis. The effects ecosystem fractions were dependent duration, grassland types climate factors. Specifically, our results indicated that had more obviously positive stock meadow than steppe. when considering longer duration was effective for increasing (
