摘　　要：我们于2006年7月对分布于青藏高原东部若尔盖高寒湿地的7只高原林蛙(Rana kukunoris)进行了追踪研究。Monte-Carlo模拟表明:在研究期内高原林蛙的运动是随机的,还没有开始迁移。高原林蛙的平均运动距离为7.1m,雌雄运动距离没有差异。95%和50%Kernel家域分别为796.2m2±704.0m2和119.9m2±94.6m2,MCP家域为157.9m2±119.5m2。雌雄高原林蛙生境选择存在差异,雄性倾向于在洞穴较多的生境中运动和隐蔽,而雌性倾向于在草丛中运动和藏匿;早晨高原林蛙选择地面温度较高、相对湿度较大的微生境活动,雌雄活动点的空气温度、相对湿度和植被高度没有显著差异。追踪个体的微生境利用表明:高原林蛙和哺乳类洞穴具有很强的相关性。Radio telemetry was used to study the ranging behaviour of plateau brown frogs Rana kuknoris during the post-breeding period. The movements of frogs were apparently random and limited in extent （ the average distance travelled by both sexes was 7.1 metres during the study period）. 95% and 50% kernel homeranges （Mean ± SD） averaged 796.2 m^2 ± 704.0 m^2 and 119.9 m^2 ± 94.6 m^2, respectively. Use of minimum convex polygon measurements yielded a home range area of 157.9 m^2± 119.5 m^2 . Habitat use differed between the sexes; males tended to use mammal burrows, while female frogs sheltered in grass clumps. However, measurements of air temperature, relative humidity and vegetation heights at sites used were very similar for both sexes [Acta Zoologica Sinica 53 （6）： 974-981, 2007].
