摘　　要：应用相似性系数分析方法 ,对新疆阿尔泰山、天山和昆仑山苔藓植物区系间的相似性进行了定量研究。结果表明 :阿尔泰山与天山苔藓植物区系之间的相似性最大 ,其科、属、种的相似性系数分别为 86 .1 1 % ,6 4 .45 %和 5 0 .45 % ,表明阿尔泰山与天山苔藓植物区系有较近的亲缘关系 ;昆仑山与天山苔藓植物区系间的相似性大于它与阿尔泰山间的相似性。In this paper,coefficient of similarity analysis was used to study flora similarity of mountain bryophyte in Xinjiang.The results show that the similarity of bryophyte vegetation between Tianshan Mountains and Altai Mountains is the highest one,among three mountains in Xinjiang.The coefficient of similarity of their families,genera and species are 86.11%,64.45% and 50.45% respectively,which indicates the bryophyte flora of Altai Mountains is close to that of Tianshan Mountains.The similarity of bryophyte vegetation between Tianshan Mountains and Kunlun Mountains is higher than that between Tianshan Mountains and Altai Mountains.The results of coefficient of similarity analysis are in accordance with results of climatic data analysis.
