江苏省云台山地蝶类多样性与区系研究

Study on the Diversity and Fauna of Butterflies in Yuntai Low Mountain,Jiangsu Province

在对江苏省云台山地采集的1 000余号蝶类标本鉴定的基础上,进行该地区蝶类多样性与区系的分析。结果表明:云台山地蝶类76种隶属7科54属,其中凤蝶科5属11种,绢蝶科1属1种,粉蝶科5属6种,眼蝶科7属12种,蛱蝶科15属18种,灰蝶科10属15种,弄蝶科11属13种。系列分析表明江苏云台山地蝶类区系基本组成为:广布种占46.05%,东洋种占35.53%,古北种占18.42%。通过与江苏省内其他山地的相似度比较,相似度的比较云台山地与宁镇山地的区系成分最为相似。由于受海洋性气候影响,云台山地蝶类区系成分与同纬度的相山山地蝶类区系成分有明显差异,说明局域微环境对蝶类区系影响很大。

Based on tai low mountain, ded. 76 species of the identification of about 1 000 specimens of butterflies collected in Yun; the diversity and fauna of butterflies of Yuntai low mountain are conclu- butterflies are classified in 7 families and 54 genus. These are Papilionidae 5 genus and 11 species, Parnassiidae 1 genus and 1 species, Pieridae 5 genus and 6 species, Satyridae 7 genus and 12 species, Nymphalidae 15 genus and 18 species, Lycaenidae 10 genus and 15 species, Hesperiidae 11 genus and 13 species. The result of a series analysis shows that the percentages of Oriental species, Palearctic species and widely distributive species are 35.53%, 18.42%, 46.05%, respectively. According to the comparison of the similarity, the fauna composition of butterflies is most kindred between Yuntai low mountain and Ning- zhen low mountain in Jiangsu Province. Because of the influence from marine climate, the fauna composition of butterflies in Yuntai low mountain is very different from Xiangshan low mountain, so we can see that regional environment impact on the fauna composition most.
