Abstract: In this study,we used a spatially explicit forest landscape model,LANDIS,to explore the succession dynamics in Huzhong Forest Bureau under two harvest scenarios: (1) the old-man trees are harvested and (2) the old-man trees are not harvested.Results showed that more over-matured cohorts appeared under harvest scenario (1) than scenario (2).Subsequently,the forest landscape component and pattern without harvest are more stable than that under harvest.Undisturbed old-man-forest is more resistant to anthropogenic disturbances (e.g.harvest).In view of this,it is recommended to reserve the old-man-forest area for the sustainable development of forest in the Daxinganling Mountain.
