As one of the most important natural ecosystems on the earth, forest ecosystems provide multiple service values such as supply services, support services, regulation services and cultural services. Fujian Province is rich in forest resources and is a pioneer demonstration zone for ecological civilization construction. Therefore, it is of great practical significance for Fujian Province to clarify the status of forest ecosystems and integrate spatial configuration in formulating scientific and reasonable ecological protection and management policies and promoting regional sustainable development. Based on the spatio-temporal perspective of geography, this paper takes the forest ecosystem service values of Fujian Province in 2000, 2003, 2008, 2013, 2018 and 2023 as the research object, uses the value equivalent method and makes three coefficient corrections to calculate the forest ecosystem service values of Fujian Province in the corresponding years. Finally, the ArcGIS gravity center model, spatial analysis and other model methods are used to analyze the evolution of the spatio-temporal pattern. The results show that: (1) The forest ecosystem in Fujian Province has a wide coverage area, and the total area shows a trend of first increasing and then decreasing, with a relatively balanced distribution. However, the forest ecosystem is gradually becoming more dispersed, and the degree of fragmentation is deepening. (2) The forest ecosystem service value in Fujian Province shows a fluctuating change trend, with a slight decrease in the total value, but the change degree is small. The regulation service value is the main part of the forest ecosystem service value, and the change trend is basically consistent with that of the forest ecosystem service value. In addition, the spatial regional distribution law of forest ecosystem service value grades in different stages is obvious, and the grade distribution of each county and district in different periods is different. (3) The spatial distribution pattern of forest ecosystem service value in Fujian Province shows a "northeast-southwest" spatial distribution trend, and the distribution center generally moves to the southwest, gradually deviating from the geometric center of Fujian Province. The coverage of the standard deviation ellipse is relatively stable, and the spatial distribution balance gradually strengthens. (4) The forest ecosystem service value in Fujian Province shows a spatial distribution characteristic of high-high aggregation or low-low aggregation, and the spatial aggregation effect of high-high and low-low types of forest ecosystem service value is relatively significant, while the spatial aggregation effect of low-high and high-low types is not obvious.
