Sensitivity analysis for main factors influencing NPP of forests simulated by IBIS in the eastern area of Northeast China
IBIS模拟东北东部森林NPP主要影响因子的敏感性

IBIS(Integrated Biosphere Simulator) model is an ecosystem process model,which requires extensive input variables involving vegetation,soil and climate,to simulate net primary productivity(NPP) and other variables.In this study,we validated the modified IBIS based on NPP measurements between 2004 and 2005 for different vegetation types in Maoer Mountain.The results showed that the modified model can be applied to simulate NPP in the eastern area of Northeast China.We also examined the sensitivities of NPP v...
