Ecosystem service function is closely related to landscape pattern evolution. Studying the coupling and coordination of ecosystem service function and landscape patterns is of great significance to regional development. Using Grain for Green Project (GGP) in the Wuling Mountain area, the distributed calculation method, landscape pattern index analysis, and coupled coordination model were adopted for the study. The purpose of this paper is to reveal the coupling and coordination between the ecosystem service function and landscape pattern of the area. The results showed that: (1) The quality of various ecological service functions of GGP increased significantly from 2005 to 2017. For example, the most significant increase in the quality of the nutriments accumulation function increased by 5.51×10⁴t/a, about 18 times of the previous. The least significant increase in the quality of the solid soil functional materials was 4404.73×10⁴t/a, about 17 times as much as before. The best spatial distribution patterns of the ecosystem services gradually expanded from the west to the south-east. (2) Time and space differences exist in the landscape evolution. The landscape patterns changed conspicuously, with changes concentrated in the central and western regions from 1995 to 2005. (3) There is a high level of coupling and coordination between GGP ecosystem services and landscape pattern evolution in Wuling Mountaina. The results can provide a scientific basis for land-use planning and GGP implementation in the Wuling Mountain area.
