Spatial-temporal changes of ecosystem service value in Sanming City
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 hm2.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.
