ABSTRACT
In order to investigate the distribution of different ecological communities of Moss in Sygara Mountain of Tibet, we investigated the Mosses and analyzed them in laboratory during 2015 and 2016. The results showed that there were 28 families, 72 genera and 136 species, including Liverwort 3 families, 3 genera and 3 species, namely: Solenostoma obovatum (Ness) Schust, Hepat, Scapania gaochieniaFu ex T. Cao Acta Bot, Conocephalum conicum (L.) Dum. As the dominant families in the area, the order was Bryaceae, Dicranaceae, Pottiaceae, Brachytheciaceae, Grimmiaceae and Hypanaceae. The habitat was divided into 4 species community types: soil, stone, tree and aquatic community. The soil community was the main body among them, and the stone and tree community were subject, and the aquatic community was the lowest.
