摘　　要：2016年5月至2019年8月,通过走样线和广泛采集的方式首次对甘南当周景区的蝶类进行了调查,采集到蝶类标本共计400余头,经整理鉴定共有39种,隶属于8科33属。其中凤蝶科1属2种、绢蝶科1属1种、粉蝶科7属10种、眼蝶科6属8种、蛱蝶科6属6种、蚬蝶科1属1种、灰蝶科6属6种、弄蝶科5属5种。其中,粉蝶科和眼蝶科为优势种群,蛱蝶科、灰蝶科和弄蝶科为常见种群,凤蝶科、绢蝶科和蚬蝶科为罕见种群。其中有27个单种属,占总属数的81.82%,单种属所包含的种类占总种数69.23%;有6个多种属,占总属的18.18%,含12种,占总种数的30.77%;属种比值系数为0.85。39种蝶类中,属于古北界的有25种,占总种数的64.11%;广布种有14种,占总种数的35.89%;东洋界无分布;即古北界分布的种类占绝对优势。通过研究该地区的蝶类资源对于甘南地区乃至甘肃的蝶类资源保护和环境质量监测提供基础资料。From May 2016 to August 2019,butterflies in Gannan Dangzhou scenic spot were investigated for the first time through walking sample-line and extensive collection.More than 400 butterfly specimens were collected and 39 species were identified,belonging to 8 families and 33 genera.Among them,Papilionidae is 1 genus and 2 species;Parnassiidae,1 genus and 1 species;Pieridae,7 genera and10 species;Satyridae,6 genera and 8 species;Nymphalidae,6 genera and 6 species;Riodinidae,1 genus and 1 species;Lycaenidae,6 genera and 6 species;Hesperiidae,5 genera and 5 species.Pieridae and Satyridae are predominant;Nymphalidae,Lycaenidae and Hesperiidae are common;Papilionidae,Parnassiidae and Riodinidae are rare.Among them,there are 27 single genera of the total number of genera,accounting for 81.82%,including 69.23%of the total species;there are 6 multiple genera,accounting for 18.18%of the total number of genera,including 12 species,accounting for 30.77%of the total species;and the ratio coefficient of genera to species is 0.85.Among 39 species of butterflies,25 species belong to the Palaearctic,accounting for 64.11%;14 species are widely distributed,accounting for 35.89%;there is no distribution in the Oriental—the Palaearctic are absolutely dominant.The study of butterfly resources in this area can provide basic information for butterfly resources protection and environmental quality monitoring in Gannan and even Gansu.
