摘要
采用主成分分析及聚类分析方法对西藏一江两河流域地区的农牧复合度进行评价和分区,得到如下结果:西藏一江两河流域农牧复合度差异极其明显,其中拉萨7县市区的农牧复合状况最好,复合水平最高,其次是日喀则地区的6县(市区),农牧复合水平最低的是山南地区的5个县(市区)。图1,表4,参13。
In this paper, principal component analysis and cluster analysis methods were used to evaluate and divide the agriculture-herding compound degree in Tibetan YLN areas. The results are as follows： the agriculture-herding compound degree varied significantly in Tibetan YLN areas. Among them, 7 counties of Lhasa have the highest agriculture-herding compound degree, 6 counties of Shigates followed, and the lowest agriculture-herding compound degree was found in the 5 counties of Lhoka region.
