甘肃太统一崆峒山国家自然保护区的蝶类群落特征

2006--2010年期间，对太统一崆峒山国家级自然保护区的蝶类进行了研究。采集到蝶类标本共计4800余号，经过整理鉴定出蝶类230种及亚种，隶属10科24亚科126属。其中36属71种为优势类群，占总种数的30．87％；眼蝶科有46种，占20．0％；灰蝶科有37种，占16．1％，为次优势类群；喙蝶科、蚬蝶科为单属单种，属于罕见类群；其他各科为常见类群。在230种蝶类中，属于古北界的种类占总种数的26．5％，属于东洋界的种类占总种数的5．7％，两界兼有种类和广布种类占总种数的67．8％，即广布种类成分最多，东洋界成分最少。230种蝶类隶属126属，其中单种属有75个，占总属的59．5％，包含的种类占总种数的32．6％；多种属有51个，占总属的40．5％，包含的种类数有155种，占总种数的67．4％；属种比值系数为0．548。结果表明，该地区蝶类区系以单种属为主。

Community characteristics of butterflies in the Gansu Taitong--Kongtongshan National Nature Reserve

The Distribution of butterflies （Lepidoptera：Rhopalocera） in Gansu＇ s Taitong-Kongtongshan National Nature Reserve was studied from 2006 to 2010. Identification of about 4 800 specimens indicated that 230 species and subspecies of butterflies from 10 families, 24 subfamilies and 126 genera were obtained. The Nymphalidae, with 71 species comprising 30. 87% of the total, were the dominant group. The Satyridae and Lycaenidae were represented by 46 species and 37 species, respectively comprising 20.0% and 16. 1% of the total. Both the Libytheidae and Riodinidae were represented by just one genus and one species. Palearctic species comprised 26. 5% of the 230 species identified, Oriental species 5.7% and widely distributed species 67.8%. 75 of the 126 genera, 59.5% of the total, were monotypic, containing species that comprised 32. 6% of the total. Fifty-one genera, 40.5% of the total, were polytypic, containing 155 species or 67.4% of the total. The ratio of genera to species was 0. 548. The results show that the butterfly fauna of this region is mainly comprised of monotypic genera.
