摘　　要：基于1985—2019年长时序遥感数据,定量核算湖南省生态服务价值(ESV),系统解析土地利用/覆盖变化(LUCC)的影响方式,模拟2030年多情景下ESV的时空演变。结果表明:湖南省LUCC显著,草地面积总体呈现持续下降的趋势,面积减少852.91 km^(2),不透水面面积持续上升,面积增加3013.77 km^(2)。湖南省ESV整体呈现先上升后下降的倒“V”形变化,总体下降了86.07亿元,主要来自废物处理、土壤形成与保护等功能变化的贡献。LUCC对ESV具有显著影响,主要增益来自退耕还林和退耕还湖,分别增益837.73亿元和111.62亿元;2030年多情景预测显示,在自然发展和经济发展情景下ESV呈现持续下降趋势,在生态保护情景下呈现上升趋势。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 systematically analyzed,and the spatiotemporal evolution of ESV under multiple scenarios in 2030 was simulated.The results showed the LUCC in Hunan was significantly,the grassland area decreased by 852.91 km^(2),while the impervious surface area continued to rise,increasing by 3013.77 km^(2).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 mainly 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.
