模糊聚类分析在森林立地分类中的应用

THE APPLICATION OF FUAAY CLUSTERINGIN FOREST SITE CLASSIFICATION

在生物学、地学分类研究中,不同的多元统计分析方法,是进行此项工作的不同的实现过程。应用模糊等价关系聚类分析方法划分四川威远林场森林立地类型,选择坡向、坡位、坡度、土壤类型等11个土壤特征作为分类属性,并结合林业基础理论知识,将有效土层厚度、B(B)层紧实度,B(B)层质地和土体通透性能等分别赋予较大的权重,同样获得了满意的分类结果。

Different multiple anlysis of statistics can be used in biology and site science. Fuzzy clustering is applied for the site classification in Forest Farm of Weiyuan County. Eleven soil properties, for examlpe, aspect, position of slope, gradiant, soil type etc. were chosen as classifing attributes, Effictive thickness of soil permeability were vested with more weight tot anlysis according to basic forestry theory. The result is satisfactory.
