摘    要:以中国西北部的阿尔泰山(哈纳斯自然保护区)、准噶尔盆地、天山、塔里木盆地、阿尔金山、阿拉善、阿西、柴达木盆地及阿里等9个地区作为植物区系定量分析的单位。在对以上地区种子植物种数建立模糊矩阵的基础上,分别应用P Jaccard系数、P F Russell与T.R.Rao系数及R R Sokal和C D Michener系数建立模糊相似矩阵R,再分别对这三个矩阵R建立模糊等价矩阵R^*,最后作归类处理

关 键 词:西北地区  种子植物  植物区系  相似性

Abstract:Quantitative comparison and analysis on seed flora in northwestern China,includingAlashan, Ali l the west of Yellow River, Aerjin Mountian, Altai Mountain, ZhungeerBasin,Tarim Basin,Tsaidam Basin,and Tianshan Mountain has made. The results indi-cated that the desert flora in northwestern China is an unity. But Zhungeer Basin flora isobviously exception. Florae in Altai Mountain, Tianshan and Aerjin Mountain showstheir own characteristics in composition,their independent way in evolution. Flora in Aliis relatively young. The results are coincided with the conclusion derived from traditionalqualitative analysis.
Keywords:Northwestern China  seed flora  quantitative analysis  resemblance
