Interview technique, field investigation and quadrat sampling method were used to study the sleeping sites selection by Macaque Mulatta in Lu Mountain, Sichuan Province. 5 sleeping sites selection were recorded in the investigation. 12 quadrates (10m*10m) and 15 habitat factors were measured and calculated with principal component analysis. The results showed that the characteristics of the sleeping sites were the area of 1600m-1700m, the middle slope position of slope land with slope of 20°- 40°, certain macrophanerophytes density, the average DBH of the sleeping tree were less than 15 cm, the sleeping height were less than 6 m, the theropencedrymion with medium concealment, less disturbed human activities. The principal component analysis showed that the first 6 factors contributed 82.242% of the total variance reflecting the characters of the sleeping sites. It was indicated that the main ecological factors affecting the sleeping sites of the Macaca mulatta in Lu Mountain were terrain, sleeping height, feeding point distance, road distance, human interference distance, concealment, slope direction, etc.
