[Objective] This study aims to assess the forest ecosystem service value in Fujian Province，providing valuable insights for ecological conservation and high-quality development in the region. [Methods] From a spatiotemporal geographical perspective， this study evaluated the forest ecosystem service value of Fujian Province for the years 2000，2003，2008，2013，2018，and 2023 using the value equivalent method with three rounds of coefficient adjustments. ArcGIS tools，including the center of gravity model and spatial analysis，were employed to examine the spatiotemporal evolution patterns. [Results] 1）Fujian's forest ecosystem exhibited extensive coverage，with total area increasing first and then declining，showing a relatively balanced distribution. However，the forest ecosystem became increasingly dispersed，with more pronounced fragmentation. 2）The forest ecosystem service value exhibited a fluctuating trend with a slight overall decline and limited variation. Regulation services were the dominant component，and their trend closely mirrored the overall service value trend. Forest ecosystem service value grades showed clear spatial and regional distribution patterns across different stages，with varying forest ecosystem service value classifications among counties. 3）Spatially，forest ecosystem service value displayed a "northeast-southwest" distribution， with the center shifting southwestward， gradually deviating from Fujian′s geometric center. The coverage of the standard deviation ellipse remained relatively stable， indicating enhanced spatial equilibrium. 4）The forest ecosystem service value in Fujian Province exhibited spatial distribution of high-high and low-low clustering，with these types of clusters being significant，while the low-high and high-low clustering effects were not obvious. [Conclusion] The results are of practical significance for identifying the full inventory of forest ecosystems and optimizing spatial allocation，thus supporting the formulation of science-based ecological protection and management policies in Fujian Province to foster sustainable regional development.
