We used 4 typical community succession stages of Alpine Kobresia meadows where stock animals graze in late autumn, winter and early spring, to explore plant functional groups (PFG) characteristics responses to different grazing intensities. The grazing intensities include freedom grazing (according to the normal grazing intensity), reducing stock-grazing intensity 50%, no grazing. The succession stages include Gramineae grass-Kobresia humilis community, Kobresia humilis community, thicken in Kobrecia pygmaea community and Cracks in Kobrecia pygmaea community. The PFGs include Gramineae, Sedge, Legumes, shrub and Forbs. All the PFGs characteristics collected in the early of June, which is the end of grazing in winter and spring pastures. The data statics were used One Way ANOVA (α=0.05) by SPSS 11.5, the results showed: the status and function of Gramineae and Sedge PFGs could be increased, but Forbs PFG could be decreased under grazing-deducing, if numerical characteristics of Gramineae PFG was greater than or equal to Sedge PFG in plant communities. While the status and function of Gramineae and Forbs PFGs would be increased, but Sedge PFG would be decreased under the grazing-prohibition based on the prerequisite above. If the status and function of Sedge PFG was greater than Gramineae, and dominate species of Sedge PFG was rhizome sparse cluster-type plants, deducing stocks grazing intensity could increase the recovering efficiency of Gramineae PFG, while if the dominate species of Sedge were dense cluster-type plants, deducing stock grazing intensity could increase the recovering efficiency of Sedge PFG, and all recovering efficiency would be promoted when the alpine meadow in grazing-prohibition. So the way to choose degradation alpine Kobresia meadows restoration method should pay more attentions to edible composition structures of forage in the community, land status of pasture and recovery goals. When Gramineae is dominate edible forage in degradation alpine meadows, grazing-reducing is the best recovery method, while if Sedge PFG is dominate edible forage, grazing-prohibition is the best recovery method. And cracks in pasture land on alpine meadows are the new plant growing area, if the intensity of cracks in pasture land is in a proper ranges, it will improve the alpine meadows recovery efficiency.
