Abstract: 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 distu rbance and source of water were selected to be analyzed by quantificat ion theory Ⅰand 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 bam boo density. The random factors were slope position and aspect.
2. Optimal habitat of red pandas in Mabian were mixed b roadleaved and deciduous forest, distance from human disturbance greater than 1 000 m; distance from water source less than 250 m.
