The Dynamics of Major Species During the First four Years Restoration from Grazing in Inner Mongolian Grassland
Grazing restoration succession of the degraded grassland is an important aspect in community ecology. Field experiment was carried out to examine how major species restore in first four years restoration following 11 consecutive grazing under different stocking rates in Inner Mongolian steppe. A. frigida and P. acaulis are the most important two species in the all treatments (NG, LG, MG and HG) after four years restoration, although they had high fluctuation. The biomasses of these two species account for 40-90% of total biomass. Especially in no grazing area, which was exclosured since 1990, A. frigida and P. acaulis are still the most important two species in the community. These results suggested a. frigida and P. acaulis community are quite stable, and will keep long-time if no special measurements were taken during the restoration of the degraded grassland.
