Abstract：The broadleaved Korean pine forest in Changbai Mountain is one of the few large-area primary mixed needleleaf and broadleaf forest in the world,so it is particularly necessary to conduct simulation research on it.This study is based on the new generation dynamic vegetation model CLM5-FATES(Community Land Model version 5-Functionally Assembled Terrestrial Ecosystem Simulator),by selecting the maximum carboxylation rate at 25℃,specific leaf area,and leaf longevity to simulate the distribution of mixed needleleaf and broadleaf forest in Changbai Mountain.This paper explores the parameter sensitivity of the distribution of mixed needleleaf and broadleaf forest in the model,and investigates the model's ability to simulate the distribution of these forests.The study finds that different combinations of trait parameters significantly affect the distribution of vegetation types in the region.The maximum carboxylation rate at 25℃and specific leaf area have a greater impact compared to leaf longevity.Under an appropriate combination of trait parameters,the model can reproduce the observed distribution of mixed needleleaf and broadleaf forest in Changbai Mountain.This study validates the applicability of the model to the mixed needleleaf and broadleaf forest in Changbai Mountain,providing crucial support for further research on climate-vegetation interactions.
