Topography-Mediated Nonlinear Responses of Soil Organic Carbon Stocks to Multi-Gradient Warming and Precipitation Shifts in Northeast China’s Temperate Mountain Forests
Soil organic carbon (SOC) in mountain forest ecosystems exerts critical controls over regional carbon balance and climate feedback loops. This study collected 209 stratified topsoil (0–30 cm) samples across temperate mountain forests of Northeast China, conducted a boosted regression tree (BRT) modeling framework integ...
