英文摘要Obtaining high-precision vegetation maps is essential for ecological monitoring and natural resource management. However, the existing 1:1,000,000 vegetation maps are manually delineated, which introduces uncertainty and subjectivity in defining boundaries, limiting their utility for detailed management and research. This study demonstrates a reproducible method for reconstructing historical vegetation boundaries with enhanced spatial precision, with a case study on the Tibetan Plateau (TP). Landsat imagery was used as the primary data source, and recursive feature elimination (RFE) was applied to optimize feature sets. Based on selected features and three machine learning models: support vector machine (SVM), gradient boosting tree (GBT), and random forest (RF), 15 classification strategies were designed to evaluate the impact of different feature-model combinations. The results show that: (1) the strategy combining the RF classifier with remote sensing, topography, and climate features optimized through RFE achieved the highest accuracy; (2) the overall accuracy of the remapped vegetation map based on this optimal strategy is 89.03%, with a Kappa coefficient of 0.88; (3) the vegetation map produced in this study has high accuracy and improves delineation accuracy compared with existing maps, showing strong consistency with actual land surface conditions as observed in remote sensing imagery. These findings provide a reliable technical approach for remapping large-scale vegetation maps, and the final vegetation map also offers valuable basic data for vegetation change research on the TP.
