甘肃尕海-则岔自然保护区蝶类群落及其区系

2012-2015年5月-9月,通过走样线和广泛采集的方式首次对甘肃尕海-则岔国家级自然保护区的蝶类进行了调查,采集到蝶类标本共计681号,经整理鉴定共有136种(亚种),隶属于8科74属。其中凤蝶科1属3种、绢蝶科1属13种、粉蝶科8属32种、眼蝶科14属19种、蛱蝶科21属32种、蚬蝶科2属3种、灰蝶科20属25种、弄蝶科7属9种。其中,粉蝶科和蛱蝶科为优势种群,灰蝶科和眼蝶科为次优势种群,绢蝶科和弄蝶科为常见种群,凤蝶科和蚬蝶科为罕见种群。136种蝶类中,属于古北界的有95种,占69.85%;东洋界的有5种,占3.68%;广布种有36种,占总种数的26.47%,即古北界分布的种类占绝对优势。通过研究该保护区的蝶类资源对于甘肃及我国蝶类研究积累基础资料。

The butterfly community in Gansu Gahai-Zecha National Nature Reserve

By using transect and opportunistic collecting methods, 681 specimens of butterflies were collected during May to September of 2012-2015 in Gansu Gahai-Zecha National Nature Reserve.Among these, 136 species, from 8 families and 74 genera, were identified: Papilionidae (1 genus, 3 species), Parnassiidae (1 genus, 13 species), Pieridae (8 genera, 32 species), Satyridae (14 genera, 19 species), Nymphalidae (21 genera, 32 species), Riodinidae (2 genera, 3 species), Lycaenidae (20 genera, 25 species), and Hesperiidae (7 genera, 9 species).Pieridae and Nymphalidae form the dominant populations;Lycaenidae and Satyridae have sub-dominant populations;Parnassiidae and Hesperiidae have common populations;and Papilionidae and Riodinidae have rare populations.Of the 136 species, 95 (69.85%) belong to the Palaearctic region, 5 (3.68%) to the Oriental region, and 36 (26.47%) were widely distributed.Species of the Palaearctic have an absolute advantage.This study provides basic information for butterfly research in Gansu and China.
