内蒙古白银库伦遗鸥自然保护区两栖爬行动物调查

Field Survey on Amphibians and Reptiles in Baiyinkulun Nature Reserve for Relict Gulls,Inner Mongolia

2006年5~9月,采用样带法对内蒙古白银库伦遗鸥自然保护区的两栖爬行动物进行了调查,共记录到两栖爬行动物12种,其中两栖类1目3科4种,爬行类2目4科8种。区系组成以古北界种类占明显优势。花背蟾蜍Bufo raddei和丽斑麻蜥Eremias argus分别为两栖类和爬行类的优势种。物种组成与附近的锡林郭勒自然保护区、赛罕乌拉自然保护区有较高的相似性。根据保护区的现状,提出了对两栖爬行动物的保护建议。

From May to September,2006,a field survey on amphibians and reptiles was conducted with the line-transect method in Baiyinkulun Nature Reserve for Relict Gulls,Inner Mongolia.A total of 12 species of amphibians and reptiles were recorded.Among them,4 species of amphibians belong to 3 families and 1 order,and 8 species of reptiles belong to 4 families and 2 orders.The Palaeoarctic species appeared dominant over the other species in this fauna.Bufo raddei and Eremias argus were dominant species.The species composition of amphibians and reptiles in Baiyinkulun Nature Reserve was highly similar to those of adjacent nature reserves.Suggestions on the conservation of amphibians and reptiles are proposed based on the results of this field survey.
