摘  要:
采用空间直观景观模型LANDIS ,以大兴安岭呼中林业局为研究区 ,研究对老头林进行采伐和不进行采伐预案下的森林景观变化动态。结果表明 ,在对老头林不进行采伐预案下 ,各物种的过熟林分布面积要高于进行采伐预案下的分布面积。老头林的存在能使森林景观组分和格局具有更高的稳定性 ,对采伐等干扰具有更大的抗性。因此 ,保护老头林对于大兴安岭森林的可持续发展具有重要的生态学意义。

摘  要:
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.
