摘　　要：高山区是高原陆地生态系统的重要组成部分,了解山地植物区系和资源特征对高原植物多样性保护及其资源可持续利用有重要的科学意义。文章采用野外样方调查、查阅标本及阅读相关文献等方法,对岗巴拉山南坡种子植物区系特点、植物的生活型以及资源植物展开研究。结果显示:岗巴拉山南坡种子植物共计148种,隶属95属35科;研究区科的组成中菊科为优势科;属的组成中没有明显的优势属出现,单种属最多,共计69属,69种,分别占总属数和总种数的72.63%和46.62%。植物区系结果表明,科的分布区系类型以世界广布型为主;属的分布区系类型上温带性质的分布型占绝对优势。研究区种子植物的生活型以多年生草本为主。资源植物可分为12个类型,其中以药用植物为主,共计80种62属26科。Alpine region is an important part of plateau terrestrial ecosystem. Understanding the characteristics of mountain flora and plant resource types is of great scientific significance for the protection of plant diversity and the sustainable utilization of the resources on the plateau. In this study, the floristic characteristics, plant life forms and resource types of seed plants on the southern slope of Mt. Gangbala were studied based on the field investigation, consulting specimens and reading relevant literature and books. The results showed that there were148 species of seed plants on the southern slope of Mt. Gangbala, belonging to 95 genera and 35 families. Compositae is the dominant family in the composition of families in the study area. There are no obvious dominant genera in the composition of genera and the single species genera is the largest genera with a total of 69 genera and 69 species accounting for 72.63% and 46.62% of the total genera and species, respectively. The floristic type of the family is mainly dominated by the Cosmopolitan, while distribution type of genera is dominated by Temperate element. The life form of seed plants in the study area is mainly perennial herbs. Resource plants can be divided into 12 types, of which medicinal plants are the main type with a total of 80 species, 62 genera and 26families.
