Through comparing effects between grazing systems and a feedlot system on the degenerated vegetation, the roles of rotational grazing system playing in vegetation recovery were investigated. The result shows that the frequency, the cover degree, the importance value and biomass of the grass with the rotational gazing are higher than those with the continuous grazing, the effect of the vegetation recovery by the rotational gazing is the same as that of the grass preserve. A relative optimized rotation grazing system under the degeneration vegetation is put forward. Suggestions for further study are discussed.
