Analysis of vascular plant resources and diversity in Machin County, Qinghai Province

Abstract

Abstract:

Machin County is situated in the Sanjiangyuan Nature Reserve in the southeastern part of Qinghai Province. Influenced by the special topography and climate of the Qinghai-Tibet Plateau, Machin County has complex and diverse plant species. The vascular plant resources and diversity in Machin County were studied through field survey, literature review and specimen identification. The results show that there are 47 families and 127 genera and 256 species of vascular plants in the region, basically angiosperms, including those containing more species of the family Asteraceae, Buttercup, Genus Ginseng, Leguminosae and Rosaceae, and those containing more species of the genus Artemisia, Artemisia, Aster and Donzonia. In terms of life type, perennial herbs are the most dominant ones, accounting for 77.34% of the total number of species, followed by some annual (or biennial) herbs and shrub types. There are 191 species of medicinal vascular plants, accounting for 74.61% of the total number of species, including 48 species of Tibetan medicine. In terms of the medicinal parts of these plants, whole herb category is the most common one, followed by the root and rhizome category. Based on the investigation and research, we have proposed the conservation and utilization of plant resources in Machin County, Qinghai Province.
