摘要
以水青冈属(FagusL.)为例,应用多元统计分析方法和原理,借助计算机作图软件,实现了植物分布在综合气候因素中的直观表达,使不同物种的气候生态位的比较成为可能;应用空间统计学方法和原理,在计算机空间分析软件和作图功能的支持下,实现了植物三维空间分布的表达。
Study on plant distribution and its relationship with climate provides a basic information for management and use of plant resources. Although study on the plant distribution _climate relationship has been carried out for a long time, little work on their numerial analysis and graphical illustration has been reported. Progress in computer software and spatial analysis and multiple statistical methods make the numerial analysis and graphical illustration possible. As an example, climatic niche and three_dimensional distribution of beech ( Fagus L.) species are presented in this paper. Results showed that the species distribution could be expressed in comprehensive climatic axes and their climatic niche could be compared, and that species three_dimensional distribution could be illustrated by means of multi_statistical methods and computer techniques. The methods showed in the present paper will provide new and powerful ways to access to graphical exhibition of ecological distribution of plant species.
