摘要
2000-2002年,对四川邛崃山系11个县(市)的小熊猫分布状况进行了调查。共完成调查样线2332条,发现有小熊猫痕迹样线130条,分布在9个县,样线平均遇见率为5.57%,样线遇见率最高的是汶川县和崇州市;估算整个山系有小熊猫栖息地面积5107.82km2,以宝兴、汶川和天全3县的面积最大,分别占总面积的34.08%、30.65%和16.61%,这3个县占总面积的81.34%;小熊猫分布密度等级最高的区域是崇州市的四川鞍子河自然保护区。在山系内7个自然保护区中有小熊猫栖息地面积2166.84km2,占栖息地总面积的42.4%。小熊猫空间分布格局极不连续,存在许多空白区域,栖息地存在破碎化趋势,应进一步加强对邛崃山世界遗产地内小熊猫种群的保护。
From 2000 to 2002, we investigated the distribution of red panda in 11 counties in Qionglai Mountains of Sichuan Province. After surveys on 2332 line transects, tracks of the species were found in 130 line transects （5.57%）, which distributed in nine counties and concentrated in Wenchuan County and Chongzhou City. The area of red panda habitat amounted to approximately 5107.82 km2, in which Baoxing （34.08%）, Wenchuan （30.65%） and Tianquan （16.61%） counties were larger than the others and counted for 81.34% of the total. The highest density was in the Anzihe Nature Reserve of Chongzhou City. In the seven reserves of Qionglai Mountains, the area of red panda＇s habitat covered 2166.84 km^2 and was 42.4% of the total. The distribution of red panda in Qionglai Mountains was discrete and existed many gaps and fragmentation trend. Thus, the protection of red panda in Qionglai Mountains should be further enhanced.
