Based on the land use data of Hechuan District collected during 2000-2009，the effects of land use changes on ecosystem service values and landscape patterns were studied． The results indicate that the areas of agricultural land and garden land decreased substantially，and in contrast，the areas of construction land and woodland increased rapidly． Meanwhile，the landscape pattern analysis showed that the patch numbers and density were lowered，the degrees of fragmentation and dominance of the landscape were dropped，and the index of diversity and evenness increased during this period． In addition，the total regional ecosystem service values grew from 197 134．6 to 204 620．7 thousand Yuan． The ecosystem service function values dropped slightly in the functions of water regulation，waste treatment and food production，while the functions such as atmosphere regulation，climate regulation，erosion control，soil formation，biodiversity，raw materials，and entertainment，showed significant improvement．
