Analysis on the rangeland degenerate gradient of Bayanbulak

摘要：

Introduction The Bayanbulak rangeland,located in the southern slope Tianshan mountain in Hejing County,Xinjiang,is 2400 ～ 3800 m above sea level.It is a perch and close mountain basin,with a total area of 13998 km2 (Xu Peng,1993).It is not only the important animal husbandry production base,but also the important water source of Kaidu River.However,influenced by global climate warming,unreasonable use and the overloaded herds,a series of ecological questions appeared such as rangeland degeneration,soil desertification,weeds spreading and so on.
