Abstract: Baoxing County, Sichuan Province, is characterized by a wide altitude difference, diverse climate, abundant animal and plant resources, and forest resources. This study is based on MODIS remote sensing inversion data from 2001 to 2020, and uses methods such as Sen trend analysis, Mann Kendall trend significance analysis, and center of gravity shift analysis to investigate the spatial distribution characteristics of net primary productivity of vegetation in Baoxing County, a habitat of the World Natural Heritage giant panda in Sichuan Province. The results show that: (1) the NPP of forest vegetation in Baoxing County, a World Natural Heritage giant panda habitat, shows an overall upward trend, with the NPP of evergreen coniferous forest and deciduous coniferous forest increasing at a rate of 5.7 g C/m². a and 10.9 g C/m ². a, respectively. The evergreen broad-leaved forest has disappeared since 2012, with a particularly significant decrease in vegetation NPP, with an average reduction of 19.0 g C/m². a, indicating an overall enhancement in the carbon sequestration capacity of the forest ecosystem in Baoxing County; (2) The forest ecosystem of Baoxing County, the habitat of the world natural heritage giant panda, has remained relatively stable in the past 20 years. The high-value areas of vegetation NPP are mainly concentrated in the southern and southeastern mountainous areas, and the ecological functions of vegetation are showing a trend of recovery. The spatial center of vegetation NPP is generally stable, with only a significant shift around 2012. However, some forest types and ecological disturbances still have important impacts on local regional functions. The average annual vegetation NPP of Baoxing County's evergreen broad-leaved forest is the highest; (3) The spatial pattern evolution of vegetation NPP in Baoxing County, the habitat of the World Natural Heritage giant panda, is stable, with high vegetation NPP areas concentrated in the southern mountainous areas, warm color areas expanding, and low value areas shrinking, indicating an overall improvement in vegetation productivity during the study period; The spatial center of gravity of vegetation NPP has local annual displacement, but the overall average annual displacement is small and the path fluctuation is limited, indicating strong stability of the forest ecosystem structure in this region. The research results are of great significance for the sustainable management of mixed forests and dominant coniferous forests in Baoxing County, a world natural heritage site for giant pandas, the restoration and reconstruction of giant panda habitats, the adjustment of forest structure and precise improvement of functions, as well as the continuous enhancement of forest ecosystem carbon sequestration capacity.
