摘要
报道了二滩水库区爬行动物2目、9科、25属、44种.它们分属古北界(1种),东洋界(38种)和古北、东洋界广布种(5种)3种成分.作者用ShannonWinener、Greerberg多样性指数和Pielou、Hurlbert均匀度指数测定水库区爬行类多样性并与相邻地区相比较.结果表明:水库区物种的多样性十分丰富(属的H′=3.0379,种的H′=2.9754);库区内随海拔升高,物种的替代性十分明显;不同生境之间随生境异质性的增大,爬行动物的相似性迅速减小.这反映出水库区爬行动物具有丰富的多样性.
Based on the recent survey data,described are 44 species of reptiles in 25 genera,9 families of 2 orders,which respectively belong to the Palaearctic(1 species)、Oriental Realm(38 species) and the extensive distribution of Palaearctic oriental Realm (5 species) by means of diversity indexes of Shannon Winener、 Greenberg and evenness indexes of Pielou and Hurlbert the authors survey the diversity of reptiles in the reservoir area and compare it with that of the neighbour areas.The authors suggest that the species diversity of the region is extremely abundant,the species replacement with the increasing of elevation is obvious and the similarity of reptiles in different habitats weakens rapidly with the increasing of heterogeneity.
