中亚热带常绿阔叶林林隙动态与森林景观格局研究——以福建省万木林自然保护区为例

Cap dynamics and landscape patterns of forest in central subtropical evergreen broad-leaved forest—A case study from Wanmulin Natural Reserve Area in Fujian Province

摘要: 采用景观生态学方法对福建省万木林自然保护区中亚热带常绿阔叶林林隙动态与森林景观格局进行了研究。结果表明，随着林隙的不断发展，林隙冠空隙斑块形状的不规则性增强，林隙冠空隙斑块形状的破碎化程度加深，而林隙冠空隙斑块的分形维数减小。林隙冠空隙的斑块分形维数小于扩展林隙的斑块分形维数。

Abstract: The gap dynamics and landscape patterns of forest in the central subtropical evergreen broad-leaved forest in Wanmulin Natural Reserve Area of Fujian Province were analyzed with landscape ecological method.The results show that the patch form is more irregular and the patch fragmentation more obvious with the gaps growing,while the patch fractal dimension gradually becomes small.The patch fractal dimension of canopy gaps is smaller than that of the expended gap.
