Abstract:: The impacts of land use change on ESV in Suiyang County from 2000 to 2005 and from 2005 to 2010 was studied based on land use maps of 2000, 2005, 2010, which were interpreted from the ETM/SPOT imageries. The conclusions were drawn as follows: (1) during the study period, cultivated land increased by 782.49 hm², woodland, grassland, waters, unused land decreased by 111.71, 29.37, 3.16, 4.23 hm², respectively; (2) the ecosystem service values had been diminished due to the land use change in 10 years, ESV decreased by 5.37×10⁶ million yuan during 2000—2010,mainly because of the change of forest land and pasture into farmland, the rate of change was -11.69, annual dynamic was -1.17. South-central change was higher than the east and north in the spatial characteristics; (3) the accelerated urbanization, population pressures, and regional economic differences were the important reasons for the spatial and temporal differences of ESV.
