By using RS and GIS technologies,the changes of ecosystem services value in Ebinur Lake basinfrom 1970to 2009were analyzed,and the responses of ecosystem services value change to land use/coverchange(LUCC)in typical arid inland lake basin were discussed based on the theory of ecosystem servicesvalue coefficient.Results showed that the land use change was significant in the basin from 1970to 2009.The areas of cultivation land and construction land increased,but the areas of other land uses decreased.Theecosystem services value in the basin changed slightly in the period and the total ecosystem services valuedecreased after an initial increase,because the areas of woodland,water body and grassland decreased.Theincrease of cultivation land area partially offset the loss of the total value,but the loss was still greater thanthe gain.The contribution of each ecosystem service value to the total ecosystem services value had a lesschange,and the service value from water conservation,soil formation and protection together with wastetreatment contributed most.Sensitivity analysis indicated that the estimated total ecosystem services value inthe study area was inelastic to the services value coefficient,the sensitivity index of ecosystem services valuefor each land use type was less than 1and therefore,the results are credible.
