摘　　要：滇西北中甸地区共有两栖类 13种 (亚种 ) ,隶属于 2目 5科 ;爬行动物 11种 (亚种 ) ,隶属于 1目 2亚目 5科。区系成分以东洋界西南区的种类占主导地位 ,两栖类占 84 6 %,爬行类占 72 7%。区系特点表现为 :区系组成单一却特有率高 ,成分古老又兼具年轻特点 ,南北动物交汇形成多样化。两栖爬行动物的种群分布与植被类型具有密切的相关性 ;为适应环境动物形态发生了较多变化。认为中甸地区是动物地理区划中的一关键地区 ,其两栖爬行类动物的调查及分类研究工作尚需进一步深入。The paper deals with the amphibian and reptile in Zhongdian area, northwest Yunnan Province. There are 13 amphibian species (subspecies), belonging to 5 families, 2 orders, and 11 reptile species (subspecies) belonging to 5 families, 2 suborders and 1 order in this area. The components of fauna are mainly composed by Southwest Subregion of China, Orient Region, with amphibian components of 84.6% and reptile of 72.7%. Characteristics of the fauna are as follows: the composition of fauna is singularity with high rare endemic species; its composition holds both characteristics of antiquity and young; animal diversification derived from northern animals moving towards south and southern animals moving towards north in Quaternary. The population distribution of amphibian and reptile in this area are corresponded to the vegetation types. Morphological modification in herpetological animal resulted from adaptation of alpine environment. The protecting actuality and countermeasure of amphibian and reptile in Zhongdian area are expatiated and discussed in the paper. At the end, fauna division about amphibian and reptile is discussed briefly. It has been considered by the authors that Zhongdian area is a key area in fauna division, and the survey and taxonomy for amphibian and reptile should be done in the future.
