<p>Assessing the changes in carbon sink disturbances is crucial for understanding urban ecosystem stability under climate change and human activities. This study proposed a novel assessment framework for carbon sink disturbance risk (CSDR), integrating the carbon sink loss with disturbance probability and applying Tapio model with Mann–Kendall trend test methods, to reveal the intrinsic driving mechanisms and external evolutionary trends of CSDR in the Ordos during 2002–2022. The results indicated that loss and disturbance probability of carbon sink initially increased, followed by a subsequent decrease. From 2002 to 2012, the proportion of high-value CSDR areas increased from 7.69%, and weak decoupling between carbon sink loss and disturbance probability made up 57.77%. During 2002–2022, the CSDR declined mainly in the eastern and northern regions of Ordos. The results show that multiple factors influence the changes in carbon sinks in the Ordos region, and the carbon sink loss due to human disturbances has been improved. The findings enhance the understanding of human-carbon interactions and contribute to research on carbon sinks and urban sustainable development.</p>
