四川省是我国小熊猫分布最多的省,约有3000-3400只。四川邛崃山系是小熊猫重要的栖息地之一,其中以宝兴、汶川和天全的面积最大。2013年4月20日四川省雅安市芦山县发生7.0级地震,天全县为重灾区,生态环境被严重破坏,部分野生动物的生存受到威胁。本文在天全县境内小熊猫的可能栖息地内,采用样线法、样方法与3S技术相结合,对小熊猫种群数量及分布进行了调查,并对重点调查区域全面踏查（调查面积为360 hm2）。调查结果表明：天全县约有小熊猫数量43-48只,主要分布在四川二郎山森林公园、喇叭河保护区、各林场以及伙石沟作业区。在重点调查区域有小熊猫1只-2只。

The Qionglai Mountains of the Sichuan is one of the important habitats of red pandas, among which the Wenchuan County, the Baoxing County, and the Tianquanthe County are larger distributional areas. On 20th, April,2013, a 7.0-grade magnitude earthquake occurred in Lushan County in Sichuan Province, and the Tianquan County was one of the most disaster area. The ecological environment was severely damaged, and the survival of some wild animals was threatened by this earthquake. In this paper, investigations were made on the quantity and the distribution of the red panda population in the possible habitats in Tianquan County by adopting the sample line method, the sample method and the 3S technique. Meanwhile, a field survey was made in key areas （ about 360 hm^2 ）. The results showed that the there were about 43 - 48 red pandas in the Tianquan County, and they were mainly scattered in the Sichuan Erlang Mountain Forest Park, The Labahe Nature Reserve, all forest farms and the Huoshigou operating area.
