摘要
根据多年的实地调查资料和相关研究资料,对新疆梅衣属(Parm eliaAch.)地衣的种类及分布区、区系特征和垂直分布特征进行了初步研究。结果表明,分布在新疆的梅衣属地衣共有6种,分别为破裂梅衣(Parm eliaerumpensKurok.)、稀生梅衣(P.m eiophoraNyl.)、脐梅衣〔P.omphalodes(L.)Ach.〕、石梅衣〔P.saxatilis(L.)Ach.〕、槽梅衣(P.sulcataTayl.)和亚广开梅衣(P.fertilisMuell.),主要分布在新疆的天山和阿勒泰山。根据对环境的适应特征和选择性,将新疆梅衣属地衣的地理分布区类型划分为:1)环低北极及北方种,包括石梅衣和脐梅衣2种;2)环北方种,包括槽梅衣和稀生梅衣2种;3)温带亚洲种,包括亚广开梅衣和稀生梅衣2种。研究结果还显示,分布在阿勒泰山和天山的梅衣属种类的垂直分布有明显差异。
The distribution area, characteristics of flora and vertical distribution of Parmelia Ach. in Xinjiang were preliminarily studied according to investigation in field for many years and research literatures. The results showed that the Parmelia distributing in Xinjiang were Parmelia erumpens Kurok. , P. meiophora Nyl. , P. omphalodes （L.） Ach. , P. saxatilis （L.） Ach. , P. sulcata Tayl. and P. fertilis Muell. , and they mainly distributed on Altay Mountain and Tianshan Mountain. According to adaptation and selection of six species of Parmelia to environment, they were divided into three geographical groups： 1 ） Circumpolar low arctic and boreal species, involving P. saxatilis and P. omphalodes ; 2 ） Circumpolar boreal species, involving P. sulcata and P. meiophora ; 3 ） Temperate Asian species, involving P. fertilis and P. erumpens. Furthermore, the vertical distribution characteristics of Parmelia on Ahay Mountain and Tianshan Mountain were very different.
