安徽歙县清凉峰自然保护区苔藓植物区系研究

本文旨在研究安徽县清凉峰苔藓植物区系。从1877份苔藓植物标本中,鉴定出417种（包括亚种、变种、变型）,隶属于62科,169属,并根据种的分布范围划出下列区系成分:1.欧亚—北美成分（97种,23.26％）;2.东亚—北美成分（9种,2.15％）;3.欧亚大陆成分（19种,4.56％）;4.东亚成分（179种,42.9％）;5.北半球广布成分（6种,1.43％）;6.中国特有成分（20种,4.79％）;7.新热带成分（9种,2.15％）;8.旧热带成分（63种,15.1％）。进而提出,清凉峰苔藓植物区系以东亚成分为主,区系组成表现为泛热带植物区系向北渗透过渡的复杂性。

A FLORISTIC STUDY ON BRYOPHYTES OF QINGLIANGFENG NATURAL PRESERVE OF SHEXIAN COUNTY,ANHUI PROVINCE

This paper deals with the study on bryophytes of Qing-Liang-Feng natural preserve of She-Xian county,Anhui province. From 1887 specimens, 417 taxa in the preserve (including species, subspecies,varieties and forms) belonging to 62 families, 157 genera were identified and classified in the following floristic elements according to their distributions: 1. Eurasian and N-American(97 taxa, 23. 26%);2. East Asian and N-American(9 taxa,2.15%);3. Eurasian(l9 taxa,4.56%);4. East Asian(179 taxa,42. 9%) ;5. Northern Hemispheric(6 taxa,l. 43%) ;6. China's Endemic(20 taxa,4. 79%); 7. Neotropical (9 taxa, 2.15%); 8. Palaetropical (63 taxa, 15. 1%). And the floristic characteristics of bryophytes in Qing-Liang-Feng could be concluded as follows: East Asian is the prevailing, Eurasian and N-American, Extensive Tropical respectively makes up an important percentage;Transition and complexity of temperate,subtropical and tropical emerge in the composition of bryophytes in which Tropical elements permeate northward and Extensive Northern elements migrate southward.
