Results showed that the soil bulk density decreased, soil water holding capacity and water content increased and the content of soil nutrient increase to some extent after the grassland scarified; the height, cover, density of grass vegetation, above and below-ground yield, proportion of excellent and good forges and grassland plant diversity all increased, the yearly average economic benefit from the grassland soil scarifying was 155 RMB/hm2 in next 3 year.
