, accounting for 16.0% of the total area of the Three-North Shelterbelt Forest. The mild, moderate, and severe degradation accounted for 11.2%, 4.0%, and 0.8% of the total area, respectively. The overall accuracy of remote sensing validation reached 86.3%, and the overall accuracy of field survey validation reached 92.4%. By constructing a degradation assessment system for the Three-North Shelterbelt Forest and identifying its degradation distribution pattern, this study could provide scientific support for the subsequent protection and restoration of the Three-North Shelterbelt Forest.
