Spatial Prediction and Performance Comparison of Soil Organic Carbon in High-Latitude Forest Soils Based on Multiple Feature Selection Methods and Machine Learning Models
Soil organic carbon (SOC) in permafrost regions is a critical component of terrestrial carbon reservoirs, and spatially explicit multi-depth mapping is essential for identifying subsurface carbon emission hotspots and supporting carbon neutrality accounting. The Kamalan River Basin in the Greater Khingan Mountains, sit...
