森林立地分类聚类分析,是根据样本(标准地)的属性和特征,用系统聚类方法按“物以类聚”的原则定量确定样本(标准地)间的亲疏关系。为了提高计算效率和绘图分析质量,现编制了PC—1500袖珍计算机聚类分析和绘制谱系图的程序。经过实践,该程序分析计算准确可靠,工作效率较高,操作方法简便,为林业工作者野外计算工作提供了方便。利用该程序进行聚类计算和绘制系统聚类谱系图,其速度比用计算器计算、手工绘图提高数十倍。
According to the attributes and characteristics of sample (standard land), the clustering analysis of forest site classification is used to determine the relationship between the samples (standard land) quantitatively by the method of systematic clustering according to the principle of “gathering things together”. In order to improve the computational efficiency and the quality of drawing analysis, a program of PC-1500 pocket computer cluster analysis and mapping pedigree is developed. After practice, the program is accurate and reliable analysis and calculation, higher work efficiency, simple operation method, which provides convenience for forestry field work. Using the program for cluster calculation and drawing system clustering pedigree, its speed than calculated using a calculator, manual drawing to enhance the number of times.
