摘  要：
合理的森林采伐方式是国内外众多学者研究的热点。中国提出"生态采伐",对于合理采伐、保护森林资源起到了极大的促进作用(唐守正,2005;张会儒等,2007;2008)。随着景观生态学的迅速发展,森林景观研究为合理采伐提供了新思路

摘  要：
Forests managed by Lushuihe Forestry Bureau were taken as a case to analyze relative influences of harvest parameters,such as cutblock size,the spatial dispersion pattern of harvest units,whether or not reserving the forest adjacency to young forest and rotation length,on forest landscape pattern.The Harvest model and neutral landscape model were used to simulate various harvest strategies.And the Apack software was used to calculate landscape indexes of the simulated results for determining the degree of influence.The results showed that big cutblock size,clustered cutblocks,reserved forests adjacent to young forests and long rotation were able to reduce degree of forest landscape fragmentation in harvest.Whether or not the forest adjacent to young forests was reserved had the greatest influence on forest landscape,and cutblock size had the second of that.
