【Abstract】 The Huangguoshn karst caves are situated in Huangguoshu area (25°40′40″N-26°0′ 15″N, 105°37′E-105°48′E), Guizhou Province, SW China. It is 150km west of the provincial captial Guiyang city, and is a world-famous scenic area with the great Huangguoshu Waterfall at its centre and many small falls around itThe present paper is based on a preliminary study of 318 speciemens of bryophytes collected from 7 Huangguoshu karst caves. The bryophytes flora consistes of 59 species and 43 genera in 21 families. Following Chen’s(1963) and Iwatsuki’s (1960) classification, there are 68 communities of bryophytes in 7 karst caves in Huangguoshu area. The ecological distribution typed of bryophytes in Huangguoshu kant caves as follows: bryophyte communities, on limestone and dolomite; bryophyte communities on limestone soil; bryophte communities on cave tufa.The phyogeographical elements of the bryoflora of Huangguoshu kant caves are maily East Asian element (45.2%), Tropical Asian elements (19%) and North the Temperate elements (11.9%). Using the Magdefran system proposed in 1982, 8 life-forms of bryophytes can be distingnished in Huangguoshu karst caves, among them, the short turfs, wefts, mats and tall turfs form predominate.更多还原
