Leymus Chinensis grassland is one of the major types in the Eurasian steppe region, however, Leymus Chinensis grassland is in heavy degradation, for example, soil compacted, good kinds of grass decreased, etc. which is owing to lack of good management for long time. So expert of China Agriculture University developed situ-vibration scarifying machine which is based on zone tillage theory, and the machine was applied to reform Leymus Chinensis grassland in 2007. Then, in year of 2009 and 2012, field observation, sampling and laboratory analysis were used to analyze the effects. The results showed that application of situ-vibration scarifying technique on Leymus Chinensis grassland improved the vegetation height, coverage, biomass and biodiversity, increased the proportion of good pasture and the animal carrying capacity. The method increased farmer's income, including 1119.0 Yuan hm^-2 a^-1 in plant production layer, or 2142.0 Yuan hm^-2 a^-1 in animal production layer, and 219.5 Yuan hm^-2 a^-1 in potential economic benefit (that is carbon sequestration). Through monitoring and analysis, it can be drawn that the situ-vibration scarifying technique is suitable for improve Leymus Chinensis grassland or other high-quality rhizome grasslands.
