Abstract:

In order to understand the current situation of threatened vascular plant resources in Kyrgyzstan, this paper took threatened vascular plants in Kyrgyzstan as the research object, and used ArcGIS software to study their species richness distribution pattern combined with existing protected area data, and analyzed their family and genus composition, threat grade, life forms, and plant resource diversity. The results showed that there were 86 species of threatened plants in 27 families, 61 genera (including subspecific grades, the same below). Angiosperms dominate, monotypic families and monotypic genera are the main components of families. In terms of threat level, there are 12 species of Critically Endangered species (CR), 22 species of Endangered species (EN), and 52 species of Vulnerable species (VU), and human activities are the most important threat factors. The life types were divided into 64 species of perennial herbs, 9 species of trees, 7 species of shrubs, 6 species of subshrubs and 1 species of annual herbs and vines. The distribution of threatened plants is not uniform at the phytogeographic area scale, and they are concentrated in the west and southwest of Gilji, and the geographical protection area of plants with high species richness is small. On this basis, some suggestions for the protection of threatened vascular plants in Kyrgyzstan were put forward in order to provide reference for the conservation of plant diversity in the study area.
