We studied the quantity and spatial and dynamic changes of land use and ecosystem service functions in Nanping City from 1995 to 2015 using of Landsat TM / ETM images in 1995, 2000, 2005, 2005, and 2015. The results show that the main land use types in the study area were forest land, cultivated land, and grassland, and the rapid growth rate of forest land was in sharp contrast with the decrease of cultivated land. In the conversion of six land use types, conversions among the forest land, cultivated land, and grassland were the most frequent. The forest was spatially schistose distribution and the grassland was clustered in the central and eastern parts, and the construction land was clustered to the central urban area, and the cultivated land was particularly broken, and the distribution pattern changes of the water area and unused land were not obvious. The dynamic changes of cultivated land, construction land, and unused land were more intense and their stability were worse, and the activity of land use in the study area was also increasing. The value of ecosystem services in Nanping was on the rise, and the contribution rate of forest ecosystem services was the highest, which accounted for more than 85% of the whole ecosystem service function, followed by grassland and cultivated land. The contribution rate of water area and unused land decreased less, while the contribution rate of unused land was minimal. Population is one of the driving factors that affect land use changes and the value of ecosystem services in Nanping.
