Plant resources and diversity analysis of Sejila Mountain in southeast Tibet

Abstract

Sejila Mountain is located in Linzhi City, southeast Tibet. The terrain is high, and the climate is cold and dry. The special ecological environment determines the richness and diversity of plant resources. In this study, the plant resources and diversity of Sejila Mountain were studied through field investigation, literature review and specimen identification. 282 plant species belonging to 199 genera and 81 families were collected from July to August in 2021. The dominant families are Asteraceae, Ranunculaceae and Rosaceae. In terms of life form, perennial herbs are the main form, accounting for 58.16% of the total. 178 species of medicinal plants were collected, including 33 species of Tibetan medicine. In terms of medicinal parts, the whole grass is mainly used as medicine, followed by roots and rhizomes. In conclusion, our study has updated the plant resources and diversity of Sejila Mountain. Based on the investigation and research, some suggestions were put forward to strengthen the protection and utilization of the plant resources in Sejila Mountain.
