AN ANALYSIS OF FLORISTIC CHARACTERISTICS AND DISTRIBUTION OF THE BRYOPHYTES OF XINJIANG, CHINA

Abstract

  The bryoflora of Xinjiang consists of 417 species and subspecific taxa distributed in 163 genera and 55 families. Among them 61 species, 31 genera, and 21 families are hepatics. The floristic characteristics and geographical distribution of Xinjiang bryophytes are analyzed. The similarity coefficients of the bryophyte genera between Xinjiang and six such regions as Altai Mountain of Russia, Mongolia, Inner Mongolia, Xizang, Qingling Mts., and NE China are calculated. The data indicate that the floristic affinities between Xinjiang and its adjacent regions are close to each other. The geographic distribution of Xinjiang bryophytes are divided into five regions:(1)Altai Mountain Region; (2)Tianshan Mountain Region; (3)Kunlun Mountain Region; (4)Jungar Basin Region; (5)Tarim Basin Region.
