摘　　要：为掌握云南楚雄武定和牟定两栖爬行动物的种类,2015年5月和7月通过样线和样点法,以及资料查阅、访谈调查和专家咨询等方法,在2县展开专项研究。结果表明:武定和牟定共有两栖类18种,隶属2目8科14属,爬行类23种,隶属3目9科17属。属于国家一、二级保护动物的各有1种,属于云南特有种类5种。在这些种类中,除4种广布种外,其余种类均为东洋界物种,多数为西南、华南、华中3区共有成分。调查到的种类及种群数量比预期的要少,就其原因进行探讨。2县所处地区刚好处于滇中,为金沙江以北和哀牢山及其以南两栖爬行动物种类分布的过渡区域。在2个县均发现了外来种牛蛙,武定县还有外来种红耳龟。外来种对土著种和生态系统的危害是不言而喻的,应该给予高度重视,监测外来种的种群动态和控制其扩散,保护当地的物种多样性和遗传多样性。In order to acquire the species of amphibians and reptiles in Wuding and Mouding counties the special research carried out by the methods of line transect survey, point sampling, consulting data, inquiry census and expert consultation etc. on May and July, 2015. The result showed that 18 species of amphibians which belong to 14 genera, 8 families, 2 orders and 23 species of reptiles belonging to 17 genera, 9 families, 3 orders were recorded in the two counties. Among them, 2 species were cataloged in the first class and second class state protected animals, respectively. 5 species were endemic species of Yunnan Province. Except 4 cosmopolitan species, the others belong to Oriental Realm and most of them were the overlapping component in the Southwest, Southern China and Central China. In this survey, the species and populations of amphibians and reptiles were less than expected. Reasons were discussed, this region of the two counties was just located at the Central Yunnan and it was the transition area of species distribution from north of the Jinsha River to Ailao Mountain and its south region. The exotic species Rana catesbeiana was found in both of the two counties and Trachemys scripta elegans was found in Wuding County. The harm of exotic species to indigenous species and ecosystem was selfevident. We should pay more attention to the phenomenon, monitor the population dynamics of exotic species and control the pervasion in order to protect local biological and genetic diversity.
