Using RS and GIS, based on the data of Landsat TM/ETM+, the paper analyzes land use/cover change and calculates their effects on ecosystem services value in the western of Jilin province from 1993 to 2003.The methods are based on ESV computing formula and ESV coefficients. The following results and conclusions could be obtained: From1993 to 2003,the area of rice paddy, woodland, unutilized and build-up land increased, among which the area of rice paddy increased most greatly and increased by 48782.72hm², while grassland, wetland, water area, dry farmland decreased, among which the area of dry farmland decreased most greatly and decreased by 34354.72hm² The total value of ecosystem services of the study area declined from ¥988.45×108 in 1993 to ¥ 921.12x108 in 2003,with the net decline of ¥ 67.33×108 during the 10-year time period; The contribution of various ecosystem functions to the overall value of the ecosystem services mainly comes from the increase in gas regulation, soil formation and disposition, food production and raw materials, while climate regulation, water conservation, recreation, waste treatment and bio-diversity conservation had a decreased effect. Raw materials increased most greatly and increased by 5.91%, while water conservation decreased most greatly and decreased by 9.60%. The sensitivity analysis suggested that these estimates are relatively robust.
