摘要:

资源冷杉是极度濒危的我国特有植物，其中的湖南省炎陵县大院资源冷杉种群是种群规模最大的种群。该研究采用点格局分析方法分析了该种群的种群分布格局，用计盒维数和信息维数研究了种群格局的分形特征。结果表明：大院资源冷杉种群的空间分布格局总体上呈聚集分布；种群的计盒维数在1.047～1.354之间，种群占据空间程度较弱；种群的信息维数在1.093～1.434之间，种群格局强度尺度变化程度较低。

Abstract:

Abies ziyuanensis is a critically endangered plant species endemic to China， and its population in Dayuan of Yanling County，Hunan Province has the largest size. In this research，the spatial pattern of A.ziyuanensis population in Dayuan was analyzed using point pattern analysis and the fractal characteristics of pattern was analyzed by applying box counting dimension and information dimension. The results suggested that A.ziyuanensis population in Dayuan presented an aggregating distribution. The box counting dimension ranged from 1.047 to 1.354，which reflected a low spatial occupation degree of the population. The information dimension of population patterns were low(1.093 to 1.434). The scale variation degree of pattern intensities was low.
