摘　　要：本研究对中国新疆博格达山周边地区大型地衣进行地衣分类学和生态学结合的综合研究,通过分析大型地衣物种多样性和分布特征,探讨影响地衣分布的环境变量与生态因子。研究结果表明:(1)分布在博格达山周边地区的大型地衣共有43种,隶属于6目、11科、15属,其中茶渍目和黄枝衣目大型地衣占优势,分别占该地区大型地衣科、属、种总数的55%、67%、81%。(2)博格达山周边地区的大型地衣组成5个样点组,分别是蓝灰蜈蚣衣+裂片石黄衣组、细片石黄衣+亚灰大孢蜈蚣衣组、长缘毛蜈蚣衣+菊叶黄梅组、地卷+暗裂芽黑蜈蚣衣组、黑蜈蚣衣+枪石蕊组,样点组的分布与环境因子密切相关。(3)在影响大型地衣分布的环境因素中海拔对地衣种类分布的影响较显著。本研究为更准确地确定博格达山区大型地衣分布规律提供科学依据。A comprehensive research on lichen taxonomy and ecology of the macrolichens around the Bogda Mountains was conducted. Species diversity and distribution characteristics were analyzed and the environmental variables and ecological factors affecting macrolichens distribution were discussed. Totally 43 species of marcolichens in 15 genera, 11 family and 6 orders were found. Among them, species of the Lecanorales and Teloschistales were dominant, accounted for 81%, 67% and 55%of the sum total of species, genera and families, respectively. Five groups were recognized, they are： Physcia caesia ＋ Xanthoria lobulata, Xanthoria candelaria ＋ Physconia perisidiosa, Physcia tenella ＋ Xanthoparmelia somloensis, Peltigera rufescens ＋ Phaeophyscia sciastra and Phaeophyscia hispidula ＋ Cladonia coniocraea. Elevation has a more significant impact on the species distribution pattern. This study provides scientific evidence for accurately determining the ecological relationship and the distribution pattern of macrolichens in Bogda Mountains.
