ABSTRACT
With the intensification of global climate change and ecological degradation, the protection and sustainable management of vegetation resources in Sichuan Province have become critical research areas. This paper, leveraging multi-source information fusion technology, integrates remote sensing data, Geographic Information System (GIS) data, meteorological data, and ground observation data to propose a high-resolution spatiotemporal prediction model for vegetation resources across the province. Using an XGBoost algorithm combined with high-precision spatial grid data, the study accurately predicts the distribution of vegetation resources and provides an in-depth analysis of the impact of urbanization on vegetation cover across various cities in Sichuan. For example, plateau areas such as Ganzi Prefecture (MEAN = 68.03, STD = 12.23) and Aba Prefecture (MEAN = 49.81, STD = 10.93) exhibit rich and uniform vegetation cover. In contrast, urbanized regions like Chengdu (MEAN = 2 6.18, S TD = 21.77) s how s ignificantly l ower v egetation c overage, a lthough t he s uburban areas around Chengdu still maintain considerable natural resource richness. The model achieved an RMSE of 8.7 and an R² of 0.82, demonstrating high accuracy and robustness. The results offer crucial insights for improving ecological management and promoting sustainable development in Sichuan Province while also serving as a technical foundation for environmental protection in other regions with similar ecological challenges.
