Based on long time series remote sensing images from 1985 to 2019,the ecosystem service value(ESV)of Hunan was quantitatively calculated,the impact mode of land use/cover(LUCC)was systematical-ly analyzed,and the spatiotemporal evolution of ESV under multiple scenarios in 2030 was simulated.The re-sults showed the LUCC in Hunan was significantly,the grassland area decreased by 852.91 km2,while the im-pervious surface area continued to rise,increasing by 3 013.77 km2.The overall ESV in Hunan decreased by 8.607 billion yuan(RMB),showing an inverted"V"shape of first rising and then declining,which was main-ly due to the functional changes of waste treatment,soil formation and protection.LUCC had a significant effect on ESV.The main gains of ESV came from returning farmland to forests and lakes,which were 83.773 billion yuan(RMB)and 11.162 billion yuan(RMB)respectively.The multi-scenario forecast for 2030 showed that ESV continued to decline under natural and economic development scenarios,and increased under ecological protection scenarios.
