[Objective] The basis of urban carbon carrying capacity was determined in order to provide scientific support for urban "double carbon" and low-carbon development. [Methods] Based on land use data for Yibin City, Sichuan Province in 2000, 2005, 2010, 2015, and 2020, habitat quality and carbon storage for Yibin City were measured by the InVEST model, an evaluation index system of carbon carrying capacity for Yibin City was constructed, and an in-depth study of the level of carbon carrying capacity for Yibin City was conducted. [Results] The carbon carrying capacity of Yibin City showed a change pattern of "first increasing, then decreasing, and then increasing" . The carbon carrying capacity scores for Yibin City in 2000, 2005, 2010, 2015, and 2020 were 0.525 4, 0.606 1, 0.506 4, 0.385 3, and 0.553 4, respectively. The degree of habitat degradation continued to deepen, and the habitat quality index showed a change pattern of "first increasing, then decreasing, and then increasing" . The carbon storage index continued to increase over time, and the carbon storage rate continued to decline. The complex system of carbon carrying capacity for Yibin City has gradually changed from an imbalanced state in 2000 to an intermediate coordination state in 2020. [Conclusion] The level of carbon carrying capacity in Yibin City is on the rise, but carbon storage and habitat quality in some areas are declining significantly.
