Abstract： Research on the spatiotemporal changes in carbon storage is an important prerequisite for achieving regional low-carbon and high-quality development based on the “dual carbon” goals. This study employed a method combining supervised classification with field surveys to extract land use information of Bayannur City using high-resolution satellite imagery data. The study quantified the spatiotemporal changes in carbon storage in Bayannur City from 2015 to 2021 based on the InVEST model. The results showed that： a） Carbon storage in Bayannur City increased by a total of 97.55 million tons from 2015 to 2021， with high-value areas concentrated in Dengkou County， Hangjin Banner， Linhe District and Wuyuan County， and low-value areas concentrated in Urad Rear Banner and Urad Middle Banner. b） Changes in land use were consistent with changes in carbon storage. Compared to 2015， cultivated land and grassland areas in Bayannur City increased significantly by 1 740.00 km 2 and 11 099.09 km 2， respectively， while unused land decreased by 13 143.96 km 2. The area of water bodies showed an initial increase followed by a decrease over the six years. Significant changes were observed in the conversion of unused land to grassland in Urad Rear Banner and Urad Middle Banner， resulting in carbon storage increases of 36.72 million tons and 58.70 million tons， respectively.
