Abstract: Relics of Shangjing Longquanfu of Parhai State is the largest site in northeast region in medieval times, which demonstrate the style and features of Tang Dynasty. However, researches about bryophyte diversity in special relics habitats remain rare. The miyagi relics is the core of protection, and it has irreplaceable scientific value. In order to fully understand the diversity of bryophytes, a total of 216 specimens were collected from 45 quadrats at 9 sampling sites. Species composition, habitat types, similarity coefficient, α diversity indexes and water ecological types of bryophytes were analyzed by adopting Excel 2010 and R 3.5.1. Main results were as follows: (1)the 35 species were recorded in total, including 1 in Hepaticae and 34(17 genera, 7 families) in Musi. Dominant families were Brachytheciaceae, Pottiaceae, Bryaceae and Entodontaceae. Dominant species were Entodon dolichocucullatus S.Okam., Brachythecium coreanum Card. and Didymodon fallax Hedw. etc. (2)Habitat types were wall(40.00%) and rock(28.89%), with soil(17.78%) and tree(13.33%) habitats took second place. Similarity coefficient was the highest between wall and rock(38.71%), while the value was zero between tree and other 3 habitats. (3)Values of Patrick, Shannon-Wiener and Simpson indexes were wall>rock>soil>tree. (4)Water ecological types were only xerophyte, mesophyte and phreatophyte, in which mesophyte(51.43%) was dominate. Above research findings have important significance and will provide basic data and scientific basis for effective protection of the miyagi site.

Key words: bryophytes, species diversity, species composition, importance value, α diversity index
