Quantitative description of ecosystem service value(ESV)in rapidly urbanized areas is an effective means to straighten out the relationship between ecological environment and economic development. Based on the three-phase remote sensing interpretation data of Chongqing Metropolitan Area, the spatio-temporal evolution characteristics and driving factors of ESV in this region from 2000 to 2015 were comprehensively analyzed. The results show that:(1)the ecosystem types in the study area are mainly forest and farmland, and the forests mainly distribute in the ‘Four Mountains’ ridges running from north to south, the farmlands mainly distribute in the flat dam trough;(2)during the period, the urban ecosystem changes most significantly, and the space expands rapidly towards the three directions of south, north and west, with an increase of 225.90%;(3)the total ESV increases from 27.851 billion yuan to 29.771 billion yuan within 15 years, with an average annual increase of 0.7%; among all ecosystem types, the ESV increases in water body is the most significant, with an increase of 60.56%; from the perspective of various types of ecological service functions, the hydrological regulation service function is the main function in the research area, and the increase is the most significant;(4)the high value density of ESV in the study area mainly concentrates in the ‘Four Mountains’ ridge, the mainstream of the Yangtze River and Jialing River, and the low mountain areas such as Taozidang Mountain in the south; in spatial change, the increase of value density mainly concentrates in the ‘Four Mountains’ and ‘Two Rivers’ mainstream, and the decrease mainly concentrates in the trough valley and Pingba area between Jinyun Mountain and Zhongliang Mountain in the west, as well as in the central urban core area;(5)the results of driving mechanism analysis show that the ESV in the study area is negatively correlated with the urbanization rate, and positively correlated with the gross forestry product, showing that ESV in the study area is coupled with social and economic development, and the reasonable regulation of economic structure can effectively enhance the value of regional ecosystem services.
