Abstract: Based on the annual update data of a map of forest resources management in Gansu Province, the carbon storage of forest land was calculated by the biomass expansion factor method and the biomass per unit area method, and the temporal and spatial variation characteristics of forest land carbon storage in the Qilian Mountains forest area of Gansu Province from 2016 to 2019 were comprehensively analyzed combined with the land use type transition matrix. The results showed that grassland, unused land, and construction land transferred 22 600 t of carbon storage to forest land. After ecological construction was strengthened, there was a trend of turning grassland, unused land and construction land back to forest land. The carbon storage of arbor forest, sparse forest and shrub forest increased by 19.20% from 2016 to 2019, of which the increase of arbor forest carbon storage accounted for 98.26%, and the carbon storage of middle-aged forests and young forests with greater potential for carbon sink growth in the future had the fastest growth rates, which were 26.70% and 26.34%, respectively.
