摘    要:调查了四川茶垭沟湿地内生活或分布的51种陆栖脊椎动物,并在种的水平上对各纲的区系分布特点进行了分析和研究。结果表明,两栖动物区域性特有种多,属种分化剧烈,种的分布型以喜马拉雅—横断山区型为主,多广布种;爬行动物具有与两栖动物相似的分布型,但多东洋种,从而有明显的东洋界分布特征;鸟类以喜马拉雅-横断山区分布型和高地分布型为主,多北方型的种,带有明显的高原区域性,广布种占绝对优势,而古北界或东洋界种成分均少;哺乳动物的分布型特点是高地型占绝对优势,多为北方型类型。通过分析指出两栖动物、鸟类和哺乳动物在区域内均表现出明显的混杂现象,文章最后还讨论了古北界和东洋界在横断山区北段的分界难以确定的问题。

关 键 词:茶垭沟湿地  陆栖  脊椎动物  动物区系  分布型

Abstract:Based on the investigation to 51 terrestrial vertebrate species living in Chayagou wetland,this paper analyses the fauna characteristics of every class on the species level.The results shows that the primary amphibian species distribution type is Himalay-Hengduan-Mountain form,among them,eurytopic species are more than components endemic to any realm of Palaearctic and Oriental.Reptile has the similar characteristics as amphibians,but Oriental species are more than other components in the wetland,so reptile has obvious characteristics of Oriental distribution type.The primary distribution types of birds are Himalay-Hengduan-Mountain and Alpine types.Mostly bird species in the wetland are boreal species and Eurytopic species occupy dominant position,so the fauna indicates obviously Alpine distribution type.For Mammals,components which belong to Alpine distribution types occupy the primary position,and most of them are boreal species.
Keywords:Chayagou wetland  Terrestrial  Vertebrate  Fauna  Distribution type
