摘　　要：2012年12月至2013年2月对版纳鱼螈(Ichthyophis bannanicus)的冬眠进行初步研究,发现5条版纳鱼螈(包括成体和亚成体)在4个冬眠洞穴内冬眠,其越冬地选择在距离水源不远的溪流岸边或者平缓的山坡,能够自行打洞或者利用其他动物废弃的洞穴进行冬眠。版纳鱼螈主要是以单栖的方式冬眠,身体呈S形或者圆形。Five hibernated Ichthyophis bannanicus （including adult and sub-adult） were found out in four caves first time in Guangxi during the field survey carried out from December 2012 to February 2013. This species chose stream bank and gentle slope of hill near water surface at 0.51 - 5.23 m in distance as their overwintering place. The constructure of hibernation caves used were simple with a depth ranged from 22.3 cm to 85.4 cm which either tunneled by themselves or abandoned by other animals. Generally, each individual hibernated alone in in the shape S or circular. The body characters of the five I. bannanicus were measured.
