为了解通道县两栖、爬行动物资源状况, 于2022年5月、7月、9月在该县域内共设置80条样线开展实地调查。调查共记录到两栖纲动物1目6科24种, 爬行纲动物2目12科40种, 分别占湖南省记录的27.59%和38.10%。通道县两栖、爬行动物的区系特征明显, 以东洋界种类为主(67.19%), 广布种次之(32.81%), 无古北界种。生物多样性计算表明, 通道县两栖爬行动物的Shannon-Wiener指数和Simpson指数分别为3.314 6和0.944 1, Pielou指数为0.797 0。区系相似性结果显示, 该县区系划分与湖南省动物地理区系划分相一致。本次调查更进一步掌握了该县域两栖、爬行动物的资源现状, 为开展两栖、爬行动物资源保护与研究提供了科学依据。

In order to understand the resources of amphibians and reptiles in Tongdao County, a total of 80 sample lines were set up in May, July and September of 2022 to carry out field investigation. A total of 24 species of amphibians belonging to 1 order, 6 families and 40 species of reptiles belonging to 2 orders, 12 families were recorded, accounting for 27.59% and 38.10% of the records in Hunan Province, respectively. It was found that the two types of animals in Tongdao County have obvious fauna characteristics: the Orien-tal species are dominated ones (67.19%), followed by widespread species (32.81%), and there are no Pa-laearctic species. Analysis of biodiversity showed that the Shannon-Wiener and Simpson indexes are 3.314 6 and 0.944 1, respectively, and the Pielou index is 0.797 0. The results of faunistic similarity showed that the faunistic division of the county is consistent with that of Hunan zoogeographic fauna. The survey made the current situation of amphibians and reptiles in the county more clearer, and would provide a scientific basis for protecting and studying the animal resources in this region.
