| 摘 要： | 云雾山自然保护区有种子植物54科163属243种(不包括栽培植物),区系分析结果表明:植物科属组成特点是少数大科包含多数的种,单种属所占比例高(73.6%),但包含的植物种数少(49.4%);龙胆科(Gentianaceae)、针茅属(Stipa)、委陵菜属(Potentilla)是云雾山草原植物区系的重要组成成分;种子植物属的分布区类型相对简单,中国特有分布属少,温带成分的绝对优势明显,占90.6%(除世界分布属);区系的起源较年轻,表现在植物的古老成分稀少;云雾山种子植物区系与六盘山和贺兰山的比较结果显示:植物区系相似性系数偏低,相对而言,与六盘山的亲缘关系较近;自然保护区的建立对于植物多样性的恢复成效显著。 |

| Abstract: | There are 243 spermatophytes belonging to 54 families and 243 genera in Yunwu Mountain Natural Reserves(excluding cultivated species).Flora analysis showed that most species belong to a few large families.Mono-species genera accounting for 49.4% of all the genera have a high proportion(73.6%).Gentianaceae,Stipa and Potentilla are important components of grasslands flora in Yunwu Mountain.The areal types of spermatophytes genera are relatively simple,few Chinese endemic genera,dominant temperate genera accounting for 90.6%(excluding cosmopolitan genera).The flora origin is young.Flora of spermatophytes in Yunwu Mountain has low similarity to those in Liupan Mountain and Helan Mountain,but the genetic relationship is closer to Liupan Mountain than Helan Mountain.The establishment of nature reserves in Yunwu Mountain achieved remarkable success to improve the recovery of plant diversity. |
