乌鲁木齐南部山区地衣生态分布与地理区系成分分析

Analysis of Ecological Distribution and Floristic Element of Lichens in Southern Mountains of Urumqi

根据在乌鲁木齐南部山区对地衣物种进行的实际调查并结合资料,初步整理了分布在乌鲁木齐南部山区的地衣种类,共有130种,分别属于22科54属。其中蜈蚣衣科(Physciaceae)和梅衣科(Parmeliaceae)的属数最多,占属总数的14.81%,种数占总种数的12.96%。将乌鲁木齐南部山区地衣的地理区系划分为广布成分、环北极成分、欧亚成分、北美成分、东亚成分、中亚成分、中国特有成分等7种类型。同时结合地衣的生长环境特征将把该地区地衣的生长类型划分为9种生态类型。

130 lichen species in 54 genera and 22 families were identified from southern Urumqi mountain were reported here. Among these species the number of genera and species in Physciaceae and Parmeliaceae occupied 14.81% and 12.96% of all the lichens genera and species in this region. The result shows that lichens flora in this region includs following seven types： Widespread species, Circumpolar arctic species, Europe- Asian species, East Asia - North American species, East Asian species, Middle Asian species, unique sepcies in China. At the same time the local lichens were divided into 9 different ecological types according to the lichens substrate and environmental condition.
