tudy on restoration effects of enclosed pasture in pastureland rehabilitation areas in northwestern Sichuan province

This paper studied restoration effects of enclosed pasture in pastureland rehabilitation areas in northwestern Sichuan province, which showed that degraded grassland started to restore and improve progressively because of eliminating grazing interference after prohibiting grazing and resting grazing. Plant variety and quantity increased, the species diversity enhanced by resting grazing forbidden grazing control. The aboveground biomass in the fenced plot was increased significantly，50.36%～88.77% higher than control. Also the height of plant community significantly improved by 36.79%～76.98%, and the total coverage was also increased by 11.49%～17.28%. The excellent forage plants started to increase while those poisonous declined. The comprehensive evaluation indicated that restoration effect of enclosed pasture in pastureland rehabilitation areas was quite good.
