摘　　要：两栖动物的多样性及其动态变化是两栖动物保护工作的前期基础。2014—2018年,采用样线法观测贵州雷公山国家级自然保护区两栖动物物种组成和种群动态变化。共记录两栖动物2目8科16属28种(亚种),其中濒危种2种,即雷山髭蟾(Vibrissaphora leishanensis)和棘腹蛙(Quasipaa boulengeri),中国特有种13种,贵州特有种4种;优势种为雷山角蟾(Megophrys leishanensis)、棘指角蟾(Megophrys spinata)、黄岗臭蛙(Odorrana huanggangensis)、沼水蛙(Hylarana guentheri)、雷山琴蛙(Nidirana leishanensis)和尾斑瘰螈(Paramesotriton caudopunctatus)。6月观测到的两栖动物物种数及个体数多于8和10月。海拔800~<1200 m的两栖动物物种数和个体数均高于其他海拔梯度,随着海拔升高,两栖动物分布逐渐减少。2014—2018年,观测到的两栖动物物种数和个体数出现不同程度的波动,但均在2018年出现最低值。The biodiversity and population dynamics of amphibians are the basis of amphibians conservation.During the period of 2014-2018,amphibian species composition and population dynamics in Leigongshan National Reserve of Guizhou Province were investigated by using the transect sampling method.The results show that:(1)a total of 28 species and subspecies were found in the survey which belonging to 2 orders,8 families and 16 genera,including 2 endangered species,Vibrissaphora leishanensis and Quasipaa boulengeri,13 species recorded only in China and 4 species recorded only in Guizhou Province;(2)Megophrys leishanensis,Megophrys spinata,Odorrana huanggangensis,Hylarana guentheri,Nidirana leishanensis and Paramesotriton caudopunctatus were the dominant species in the reserve;(3)more amphibians were observed in June than in August and October;(4)the number of species and individuals of Amphibians at altitudes of 800-<1200 m were higher than those at other altitudes;(5)the number of species and individuals observed over the five years were with varying degrees of fluctuation and all bottomed out in 2018.
