摘　　要：利用2005、2010、2015和2020年的遥感数据,提取不同的土地利用类型,采用修正后的当量因子法分析三明生态系统服务价值的时空变化.研究结果表明,三明的土地利用类型发生了显著的变化.其中,森林面积的变化最为显著,转出了3638.08km^(2).三明生态系统服务价值正逐渐减少,从2005年的1487.13亿元减少到2022年的1470.00亿元,三明森林生态系统对生态系统价值的贡献超过80%.此外,三明各个生态系统的生态服务价值变化也呈现多样化的趋势,除了森林生态系统的价值减少之外,其他生态系统的价值都有不同程度增加.The study utilized the remote sensing data from 2005,2010,2015,and 2020 to extract different land use types.Through the application of a modified equivalent factor method,a comprehensive spatiotemporal analysis of Sanming′s ecosystem service values was conducted.The research findings indicate significant changes in Sanming′s land use types,with the most pronounced alterations occurring in forest areas,which ex-perienced a reduction of 3638.08 hm^(2).Concurrently,the ecosystem service values in Sanming are gradually de-clining from 1487.13 billion yuan in 2005 to 1470.00 billion yuan in 2022.Notably,the contribution of San-ming’s forest ecosystem to the overall ecosystem value exceeds 80%.Furthermore,the variations in the ecosys-tem service values of different ecosystems in Sanming exhibit diverse trends.Besides the decline in the value of the forest ecosystem,the values of other ecosystems have increased with varying degrees.
