新疆荒漠林下土壤的模糊聚类分析

本文收集了10个新疆荒漠林下土壤样品,每个样品选择6个变量,原始数据经标准化处理后,进行了模糊聚类分析.计算结果,将原分类的林灌草甸土和盐土两个类型,聚类为荒漠灌木林土、棕漠林土、棕漠林盐土、荒漠灌木林盐土四类.结果表明,在测量数据正确、选用土壤样品适当的情况下,模糊聚类分析是研究新疆荒漠林下土壤分类的一种有效方法.

Fuzzy Cluster Analysis of the Soil under Desert Forest in Xinjiang

Ten samples of desert soil were collected in Xinjiang,and six variables were picked out from each.Then fuzzy cluster analysis was carried out after the orig-ginal data were standandizedly processed.The result is that two types of soil,forest irrigation soil and solonchak,changed in to four.They are desert forest soil,brown desert forestsoil,brown desert forest solonchak and desert shrub forest solonchak.The result shows that based on the data properly collected,fuzzy cluster analysis is an effective way of studying the classification of soil under the desert forest in Xinjiang
