Influence of fencing on Seriphidium transillense pasture in Yili region of Xinjiang

This paper compared plants vegetation and soil inside and outside of the fencing in Seriphidium transillense pasture in 2005, and analyzed the effects of fencing on plant vegetation and soil. The result showed that plant height, aboveground biomass and cluster of Seriphidium transillense had an obvious increase after enclosure. The soil quality was improved, the soil bulk density inside fence was less than that of the outside, but soil water content increased, especially in 5～10 cm soil layer. The plant components of the pasture had no obvious change, but the proportion of dainty grasses increased remarkable. In conclusion, enclosure improved plant growth and the quality of pasture.
