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.
