摘　　要：１９９１年和１９９２年作者在马边自然保护区设点对与小熊猫生存有关的生态因子（植被型、竹子密度、郁闭度、坡向、坡位、水源和人为干扰）进行了调查统计。利用数量化理论分析后发现：影响小熊猫生境选择的主要生态因子是植被类型、水源和人为干扰，其次是郁闭度和竹子密度，而坡位和坡向的影响不明显。小熊猫的最适生境为离水源较近（＜２５０ｍ）、人为干扰较远（＞１０００ｍ）和郁闭度及竹子密度适中的常绿落阔混交林。The habitat selection by red pandas (Ailurus fulgens) was studied in Mabian Dafengding Reserve, Sichuan province from July 1991 to November 1992. Eight ecological factors such as vegetation type, food availability, sheltering, aspect, slope, slope position, human disturbance and source of water were selected to be analyzed by quantification theory Ⅰ and Ⅱ. The results showed as follows. 1.Among eight ecological factors mentioned above, the main factors notably influenced on habitat selection of red pandas were vegetation, source of water and human disturbance. The secondary factors were sheltering, slope and bamboo density. The random factors were slope position and aspect. 2.Optimal habitat of red pandas in Mabian were mixed broad leaved and deciduous forest, distance from human disturbance greater than 1 000 m, distance from water source less than 250 m.
