摘要
运用主成分分析法和聚类分析法,对贵州喀斯特地区的生态经济类型进行了划分。首先建立指标体系,并运用主成分分析法对22个类型划分指标进行筛选。再运用模糊聚类方法,将贵州喀斯特地区75个县(市)划分为5个生态经济类型。最后对各类型进行了分析,提出了其生态经济的发展方向,为制定区域可持续发展战略提供了科学依据。
The karst area in Guizhou Province was classified into five eco-economic categories by the principal component analysis and fuzzy poly-class method. Firstly, classification index system was set up, then was selected in 22 original variables by the principal component analysis.
