| 摘 要： | 不同植被带绢蝶Parnassius spp.生物多样性研究结果表明,绢蝶物种的丰富度由大到小为:亚高山灌丛草甸带(6种)>高山亚冰雪稀疏植被带,山地森林草原带(3种)>山地草原带(2种)>冰雪带(0种);多样性指数由大到小为:亚高山灌丛草甸带(0.785 8)>高山亚冰雪稀疏植被带(0.606 3)>山地森林草原带(0.112 4)>山地草原带(0.024 3)＞冰雪带(0).山地森林草原带和山地草原带的相似性系数最高(0.667),没有5个植被带共有的绢蝶种. |

| Abstract: | The parnassians' vertical distribution of Si-Da-Long forest-pastoral areas in Qilianshan Mts. (northern slope) is comparatively clear. Except ice-snow zone, alpine sub-ice-snow rare vegetation zone has 3 species, subalpine scrub-meadow zone has 6, mountain forest-steppe zone has 3, mountain steppe zone has 2. The subalpine scrub-meadow zone is the most concentrated vegetation zone for the distribution of parnassians, its climate, vegetation and altitude are wonderful for parnassians to survive and develop. The study of parnassians biodiversity in different vegetation zonesSi-Da-Long forest-pastoral areas in Qilianshan Mts.(northern slope)] illustrated that the species richness decreased in the following sequence: Subalpine scrub-meadow zone(6 sp.) >alpine sub-ice-snow vegetation zone =mountain forest-steppe zone (3 sp.) >mountain steppe zone (2 sp.) >ice-snow zone(0 sp.). The parnassians' biodiversity index decreased in-subalpine scrub-meadow zone(0.785 8) >alpine sub-ice-snow vegetation zone(0.606 3) > mountain forest-steppe zone (0.112 4) >mountain steppe zone ((0.024 3)) >ice snow zone(0 ) . The parnassians' species composition between mountain steppe zone and mountain forest-steppe zone had the highest similarity (Jaccard index=0.667). There is no same species in five vegetation zones. |
