[Objective] We aim to analyze the flora and utilization of vegetation resources in the margin of Badain Jaran desert, in order to provide theoretical basis and reference for vegetation restoration, protection and utilization in Badain Jaran desert.[Methods] Based on the principles and methods of geobotany, combined with field investigation, this article systematically discussed the composition and distribution of flora in the margin of Badain Jaran desert. The types of desert vegetation resources were divided and the protection measures and methods were proposed.[Results] The vegetation in the margin belonged to typical desert flora. There were 32 species belonging to 30 genera in 13 families in the study area, including gymnosperms (1 family, 1 genus and 1 species) and angiosperms (12 families, 29 genera and 31 kinds). Influenced by topography, landform, climate and other habitats, the distribution of flora showed significant differences. The vegetation resources could be classified into four types:edible or feeding vegetation(22 species), medicinal vegetation(12 species), ecological vegetation(17 species) and other resources. The article proposed conservation methods such as migratory species, species richness and diversity, and summarized the methods of controlling water resources, reasonable grazing, proper sealing, rational utilization of medical vegetation, and comprehensive utilization of resources.[Conclusion] The analysis on vegetation in the margin of Badain Jaran desert is of great importance for desertification control and of desert resources utilization.
