| 摘 要： | 克拉玛依有种子植物44个科198属369种,通过对该地区种子植物科属的区系地理成分分析,表明该地区的种子植物单种科,单种属多,区系优势现象明显:本地区中的7种优势科,虽只占克拉玛依植物区系总科数的15.91%,但所含种数占总种数的67.75%。特有种比例低,珍稀濒危保护植物种类较少,且植物区系主要以温带为主:温带分布科占总科数的57.80%,植被分布符合该地区地带性特点。

| Abstract: | In this paper,the floristic constitution and geographical elements of families and genera of seed plants in Karamay were analyzed.There are 198 species of 369 genera,belonging to 44 families.The results showed: there are many single-families and single-genera,the flora dominance is obvious. There are 7 dominant families,which occupies 6.66% of total families,but they contain 69.00% of total species.The percent of endemic species is low,rare and endangered plants are scarce.The spermatophytic flora represents mainly in temperate,including the temperate distribution pattern plant(57.80%). |
