| 摘 要： | 应用分形理论的计盒维数、信息维数和关联维数研究了太白红杉的种群格局特征.结果显 示,(1)太白红杉的种群格局具有自相似性;(2)种群分布格局分形维数可以揭示种群分布格局的尺 度变化特征,利用计盒维数、信息维数、关联维数综合分析种群分布格局能够更全面的对其进行描 述,单纯利用一个维数会导致片面的理解;(3)太白红杉种群分布格局受到人为破坏后,其分形维数 也会受到严重影响.

| Abstract: | The fractal dimension of distribution pattern of Larix chinensis is studied by using box-counting dimension, information dimension and correlation dimension. The result shows that: (1) The distribution pattern of Larix chinensis satisfies self-similarity law. (2) The fractal dimension of distribution pattern can reveal its character of the measuring level changing. The results by using box-counting dimension, information dimension and correlation dimension synthetically are more accurate than using only one of them. (3) The fractal dimension of the Larix chinensis will be different from normal, if its distribution pattern was destroyed. |
