摘    要:目前植被格局研究存在一些问题,分形模型是解决这些问题的有力工具。选择从分枝到景观的各个等级层次上若干有代表性的研究实例进行介绍。给出了尺度,自相似性和分形维数在植被格局研究中的应用方法,说明了分形模型描述植被格局的实用性和优越性。在此基础上提出了植被格局的分形机制,认为植被格局是具有自组织特征的分形体。最后对植被格局的分形模型进行了评价,提出了研究中需要注意的若干问题以及未来的发展方向。

关 键 词:植被格局  尺度  自相似性  分形维数  分形模型

Abstract:Some shortcomings existed in present vegetation pattern analysis,fractal geometry is considered to be an useful tool to deal with those problems.Selected researches on different levels,that is,from branching to landscape,were introduced first,the application of scale,self similarity and fractal dimension in vegetation pattern analysis were then explained,and the fitness and challenges of applying fractal model in vegetation pattern analysis were pointed out at last.On the basis of the above discussions,the fractal mechanisms of vegetation pattren was declared,which means vegetation pattern can be regarded as a fractal with self organizing properties.The fractal model of vegetation pattern was evaluated and prospected,some problems need to be cared about in research were put forward,and some future developing directions were predicted at the end of the paper.
Keywords:Vegetation pattern  Scale  Self  similarity  Fractal dimension  Fractal mechanism
