秦岭南麓宁东段夏季蝶类物种多样性分析

Analysis on Butterfly Diversity in Ningdong Section of Southern Qinling Mountain

为给秦岭南麓宁东段的生态保护提供数据支持,对该地区的夏季蝶类多样性进行调查。结果表明,该地区共有蝶类6科24属41种。物种多样性分析显示,该地区生态环境良好,蝶类资源丰富。其中,粉蝶科物种多样性、优势度和均匀度指数均比其他科高,表明粉蝶科种类丰富,优势种群突出;蛱蝶科物种丰富度最高,但物种多样性、优势度和均匀度指数与粉蝶科和凤蝶科相比较低;眼蝶科、灰蝶科和弄蝶科物种多样性指数、优势度指数、均匀度指数和物种丰富度都很低,表明该地区眼蝶科、灰蝶科和弄蝶科种类较少。

In order to provide data support for ecological protection in Ningdong section of southern Qinling Mountain,butterfly diversity in this area in summer was investigated.Results showed that there were 41 butterfly species belonging to 24 genera of 6 families.Species diversity analysis showed that this area had good ecological environment and rich butterfly resources.Indexes of species diversity,dominance and evenness of Pieridae were higher than those of other families,which indicated Pieridae was rich in species with dominant populations.Species richness of Nymphalidae was the highest,but indexes of species diversity,dominance and evenness were lower than those of Pieridae and Papilionidae.Indexes of species diversity,dominance,evenness and species richness of Satyridae,Lycaenidae and Hesperiidae were very low,which indicated rarity of species in these families.
