Protection of natural ecological system and environment is one of critical tasks for ecological civilization construction in China. In recent years, research on land use change and ecosystem service has become a hot spot in the field of ecosystem management in China. In the study, the ecosystem service provision index (ESPI) was proposed by the quantification of different types of ecosystem services using a synthetic index in China. The result indicated the areas of wetland, water, forest, grass, and desert ecosystems accounted for 1167.9×104 ha, 3351.6×104 ha, 25299.2×104 ha, 28457.8×104 ha, and 16397.0×104 ha in 2015, respectively. The area of farmland ecosystem accounted for 16012.0×104 ha, or 16.9% of the total land survey area. There were considerable geographic variations in distribution of land use and ecosystem service provision index due to differences in the natural environments, population density, and economic growth in China. The ecological provision capacity was found to be strongest in Fujian, Jiangxi and Heilongjiang provinces with high ESPI value. Moreover, ESPI value was higher in the Qinghai Tibet Plateau which is the source of the three major river systems in China. As one kind of artificial ecosystems, farmland ecosystem mainly distributed in the eastern region also had an important role for regional ecosystem service. There was considerable geographic unbalance between the distribution of population and the supply of ecosystem services.
