| Abstract: | According to interpreting the LANDSAT TM/ETM images of 1986 and 2002, the spatial-temporal characteristics of land use changes were analyzed during 16 years base on GIS. In addition, the change of ecosystem services due to land use change was estimated by the method of vaulting global ecosystem services. The result shows that there were rapid increases in the area of cropland, saline-alkaline land, and dramatic decreases in grassland, water area and wetland between 1986 and 2002. The annual value of the ecosystem services was declined from 767.1×108 Yuan/a in 1986 to 624.1×108 Yuan/a in 2002, the estimated annual ecosystem service value declined by 18.6% (i.e. 1.6% per year) between 1986 and 2002. It indicates that there had been a sever harm to ecosystem functions and services, which results from the deterioration of ecological environment and the adjustment of land use that aim to currently economic benefit.
