摘　　要：2008年8月和2009年6～7月间对内蒙古自治区达乌尔国际自然保护区的两栖爬行动物进行了考察,共发现8种,隶7属7科,均为古北界区系成分;以花背蟾蜍、黑龙江林蛙、白条锦蛇为优势种。基于草盖度与两栖动物多样性相互关系的监测结果显示,草原退化对两栖动物多样性构成了严重威胁;结合两栖爬行动物的分布格局和生境特点,提出了达乌尔国际自然保护区(中国)的两栖爬行动物重点保护区域和关键生境。The herpetological survey was conducted in the Dauria International Protected Area （DIPA） in Inner Mongolia Autonomous Region, China between 2008 and 2009. Eight species belonging to seven genera, seven families were collected. All species were components of the Palaearctic realm. Bufo raddei, Rana amurensis, and Elaphe dione are dominant species of the DIPA. According to the decreasing quantity of species with the tread of grassland coverage slowing down, we think grassland degradation has threatened the diversity of amphibians. Furthermore, the relationships of biodiversity and distribution patterns were studied and the main conservation areas and important habits were given.
