Abstract
The experiment on grazing systems was conducted in the typical steppe with sheep.The results showed that the standing crop, production and growth in rotational grazing were higher than that in continuous grazing(P0.05) in the drought year.There was no significant difference(P0.05)on standing crop,production and growth in two grazing systems in the normal year. The density, height,coverage and importance value of dominant species in plant community in rotational grazing were higher than that in continuous grazing(P0.05) in the two years.
