新疆博格达山苔藓植物的研究

STUDY ON THE BRYOPHYTES ON MT. BOGDA, XINJIANG

本文主要根据作者1988年至1990年间在博格达山区的六次野外考察所采的2000余号苔藓植物标本,经过整理鉴定,现已知博格达山有苔藓植物211种(变种、变型),隶属于37科、89属,其中11科、31属、111种为新疆首次记录,在分类的基础上,作者进一步对该地区苔藓植物的区系成分、生态群落特征等作了较详细的研究。

Mt. Bogda is located in the middle of the Xinjiang Uygur Autonomous Region, Northwest Chins. Its main peak, Bogda Peak (43°48′N. Lat. and 88°18′E. Long) is 5 445 m above sea level and is the highest peak in the east of the Tianshan Mountains, and its base is only about 700 m above sea level. Its summit is covered with snow year-round. The vertical variations of the climate, soil and vegetation zones is quite clear. In the present study, the author has identified more than 2000 specimens of Bryophytes, most of which were collected by the author himself from the mountain during the past six investigations from 1988 to 1991. According to this preliminary research, 211 species including varieties and forms belonging to 37 families and 89 genera are now known to be on Mt. Bogds. Among these, 11 families, 31 genera and 111 species are the first to have been found in Xinjiang. The superior families are Pottisceae, Bryaceae, Brachytheciaceae, Amblystegiaceae, Grimmisceae, Mniaceae and Hypnaceae in the species number. Based on all the research above, the floral elements and its communities of bryophytes on the mountain are also discussed in detail in this paper. In addition, a list of bryophytes on Mt. Bogda is presented.
