Land use change in Xinjiang Wei Autonomous Region from 1996 to 2008 and ecosystem services value change caused by it were quantitatively analyzed based on Xie's coefficient of ecosystem services value and ecological sensitivity analysis.A thorough and careful study of the human factors that affect ecosystem services value change in Xinjiang region was made from the aspect of qualitative and quantitative analysis.Results showed the ecosystem services value totaled 7.06 × 1011 yuan in 1996 and increased to 7.17× 1011 yuan in 2008

representing an increase of 1.07× 1011 yuan from 1996 to 2008 and an accelerated rate of increase.Waste treatment and water conservation were the two large service functions

contributing about 41.3%of the total service value

raw materials had the smallest service function

and the each type of ecosystem services values showed an increasing trend.Xinjiang region lost 8.2 thousand yuan per capita in ecosystem services value and the population growth has led to increased pressure on the environment.It reveals that the major human factors that have influenced the ecosystem services value change are economic factor

population factor and urbanization development level factor.The ecosystem services value is correlated negatively with population factor and urbanization factor

but positively with economic development level factor.
