Analysis of the Ecological Distribution and Floristic Element of Aspicilia Lichens in Xinjiang

  • 摘要: 根据多年的实地调查资料和前人研究资料,对新疆平茶渍属(Aspicilia)地衣的种类以及它们的分布区、区系特征进行了初步研究。结果表明,分布在新疆的平茶渍属地衣共有33种,主要分布在天山、阿勒泰山、昆仑山和准噶尔盆地。根据它们对环境的适应特征和选择性,将新疆平茶渍属地衣的地理区系划分为广布种、环极北极高山种、环极低北极及北方种、北美东部种、中亚种、中国特有种、分布范围不清楚的种等7种类型。同时把新疆平茶渍属地衣的地理分布区域划分为欧亚森林植物亚区、亚洲荒漠植物亚区、青藏高原亚区等三种分布区域。研究还发现分布在阿勒泰山、天山、昆仑山和准噶尔盆地的平茶渍属主要生长在岩石上面,生长基物比较单一。

     

    Abstract: In this paper we preliminary investigate Aspicilia lichens distribution area,flora characteristics according to the many years’ results on the spot investigation and research report of the other people.As the results shows that,there are 33 different lichens species of genus Aspicilia distributed in Xinjiang,and they mainly distributed on Altay mountain,Tianshan,Kunlun mountain and Zhonggar basin.At the same time,according to the Aspicilia lichens adaptation characteristics and selection of environment,we divided these species into following seven geographical groups:wide distributed species;circumpolar arctic alpine species;circompolar low artic and boreal species;north American arctic species;middle Asia species;endemic species of China and species with unclear ranges species.We also divided them into following three geographical distribution area:Euro Asia forest sub region Asia desert sub region and Qinghai Tibet plateau sub region.
