摘　　要：2018年6和8月采用样线法对云南玉龙雪山两栖动物多样性进行2次观测。设置11条样线,共记录到1143只个体,包括成体、亚成体和幼体,鉴定出2目6科8属8种。个体数量在不同季节相差较大,6和8月分别记录到705和438只。各条观测样线两栖动物物种数和个体数受平均水温、气温和人为干扰强度等因素的影响明显,表现为平均水温和气温越高、人类干扰强度越弱,物种数及个体数越多。不同生境下两栖动物物种数和个体数不同,人工水渠物种数最多,河流物种数最少。这些结果表明,生境类型、水温、气温和人类干扰是影响两栖类物种多样性的重要生态因子。In June and August 2018,the diversity of amphibians of Yulong Snow Mountain was observed by the application of sample line method.Total number of 1,143 amphibians which includes number of adults,sub-adults,and juveniles on 11 sampling transects were recorded.These individuals were identified as 8 species,which belong to 2 orders,6 families and 8 genera.The numbers of individuals vary greatly in different seasons,705 amphibians were recorded in June,and 438 in August.The numbers of species and individuals of amphibians recorded by each sampling transect were obvious and affected by several factors,such as average water temperature,average air temperature and human interference intensity.It demonstrates that the higher the average water temperature and the average air temperature and the weaker the human interference intensity on the sampling transects,the more the number of species and individuals recorded.The numbers of species and individuals of amphibians were different in each habitat.In artificial channel the number was the largest while in the river it was the smallest.From the results it could be concluded that the habitat type,water temperature,air temperature and human interference are important ecological factors affecting amphibian species diversity.
