Bryoflora, Ecology And Travertine Deposition Of Bryophytes In Malinghe River Valley

Based on the extensive investigation,collection, identification of the byophyte specimens and the study of documents, there are 250 species of bryophytes belonging to 105 genera of 41 families in Malinghe River Valley, of which 43 species are Hepaticae species belonging to 27 genera of 16 families, 2 species are Anthocerotae species belonging to 2 genera of 1 family and 205 species are Music species belonging to 76 genera of 24 families. Pottiaceae and Hypnaceae are the dominant families and Fissidens and Bryum are the dominant genera.49 species are new records of Guizhou provence , Neckeropsis moutieri (Broth. et Par.) Fleisch.is a new record of China.The floristic geographical elements of bryophyte species are complex,including 14 types.Tropical elements and Temperate elements are higher,Endemic to China and East Asia elements are also high.This paper studied the floristic geographical elements, the connection with other 11 areas,through the Statistic Analysis of Floristic Spectrum, Principal Compoments Analysis, Agglomerative Classfication Analysis, and Abundance Index Analysis.The bryoflora of Malinghe River Vallely,Jizu Mountain and Jiucaiping areas are much closer, and Abundance Index of Malinghe River Vallely is higher. Tianxing area is the best high in the distribution of families,genera and species , Maling area is the least.5 communities can be classified , Petrophytia , Geophytia ,Travertine communities,Epixylophytia , Hydrophytia. 7...
