大别山主峰天堂寨地区蝶类资源及区系组成研究

在2007~2009年间对大别山主峰天堂寨地区的蝶类进行调查,共采集到蝶类163种,隶属于10科99属,其中东洋界种76种,古北界种35种,广布种53种,分别占总数的46.34%、21.34%和32.32%,表明该地区是东洋界与古北界的过渡带;应用Jaccard相似性系数对天堂寨地区蝶类的相似性进行了分析,结果表明桃花冲森林公园与鹞落坪保护区相似程度最低,罗田天堂寨与安徽天堂寨的相似程度最高,表现在蝶类种类上也是相似度最高的.

Resources and fauna compositions of butterflies of Tiantangzhai area of Dabieshan main peak

The butterfly resources and fauna of Tiantangzhai areas of the Dabieshan main peak were surveyed from 2007 to 2009.A total of 163 species from 99 genera in 10 families were idenitified based on butterfly specimens collected in the survey.Among these,the numbers of Orienal,Palaearctic and Widespread species counted for 46.34%、21.34% and 32.32% of the total,respectively.This fully demonstrated that the region was transition zone of the Oriental and Palaearctic.Jaccard similarity coefficient was applied to analyze butterflies floristic composition of four butterfly areas.Results showed that：similarity degree of Forest Park of Taohuachong and Yaoluoping protected areas were low,similarity degree of Anhui Tiantangzhai and Luotian Tiantangzhai were high.In latter,similarity of the species of butterflies was the highest.
