湖北省蝶类分布格局研究

Study on Distribution Pattern of Butterfly in Hubei Province

对湖北省已知478种蝶类中有具体分布的427种的分布格局进行研究,并讨论478种蝶类的区系组成,以研究湖北省蝶类地理分布。分析研究认为,427种蝶类分布在44个县市,蝶类资源分布不均,不同蝶类的分布区域存在很大的差异,在10个以上县市有分布的种类只有37种,占有具体分布的蝶类种数的8.7%,总体分布呈鄂西南山区、鄂东北山区、鄂东南山区三角形分布的格局,以鄂西南山区最多,鄂西北山区和江汉平原较少。通过对478种蝶类进行区系分析,东洋界种类317种,占66.3%,古北界种类94种,占19.7%,广布两界种类67种,占14.0%。区系分析结果表明,湖北省蝶类区系应划归东洋界。

The fauna composition of the 478 reported butterfly species in Hubei province,and the distribution pattern of 427 species with concrete distribution out of the 478 species was analyzed to work out the geographical distribution of butterfly in Hubei province.The results indicated that distribution of butterfly resources was imbalance as the 427 butterfly species distributed in 44 counties and cities;and the distribution region of different butterfly varied widely.Only 37 species were reported in more than 10 counties and cities,accounting to 8.7% of all the species.The general butterfly distribution pattern in Hubei was a triangular figure including Southwestern Mountainous Area,Northeastern Mountainous Area and Southeastern Mountainous Area.There was more butterfly species in Southwestern Mountainous Area while fewer butterfly species in Northwestern Mountainous Area and Jianghan plain.Among the 478 butterfly species,317 species（66.3%） belonged to Oriental Region;94 species（19.7%） belonged to Palaearctic Region;and 67 species（14.0%） were widespread species.Based on the butterfly fauna,the zoogeographical region of butterfly in Hubei should be put under Oriental Region.
