摘要
对青海孟达国家级自然保护区野生种子植物进行了野外实地调查,同时,对相关文献进行了查询和分析,结果表明,孟达国家级自然保护区野生种子植物共计有79科325属664种。其中,温带分布的科占据优势,其次为世界分布和热带分布。属的分布上,温带分布占据绝对优势,世界分布、热带分布、东亚分布和中国特有分布为辅,并有极少其他分布类型。同时,与青海植物区系进行比较,显示两者存在明显差异。系统的分析结果显示:该地区有明显的边缘分布特征;植物的垂直分布呈现一定的规律性;该地区植物资源丰富,国家珍稀物种及有经济价值、药用价值的植物众多,观赏植物更为广布。
Based on the investigation and the floristie statistics and analysis of the wild seed plants from Mengda, there were 664 species of wild plants, belonging to 79 families and 325 genera. The areal-types of the dominant families was temperate distribution, the following types are cos- mopolitan and tropical distribution. To the distribution of the genus, the temperate distribution is dominant in this area, accompanied by tropical distribution, cosmopolitan, east Asia distribution and endemic to China distribution. There also have little other distribution-types in Mengda. Meanwhile, comparing to the flora of Qinghai Province, shows that there have obvious differences. Systematically analysis reveals that ：There has obvious marginal distribution characteristic for the plants in this area ; The vertical distribution of plants appears to be regular; There are rich plant resources in the area, rare soecies and plants with medicinal and ornamental value widely distributed in this area.
