Abstract: The slope habitat of Macaca thibetana was described by processing data made available in varying degrees from different institutions and those collected in our observations.The only primate species in the area was mainly restricted in the evergreen broadleaf (EB) and the EB-deciduous broadleaf (DB) mixed forest zonations.Variations in temperature and precipitation were obvious across seasons and very small across years in the subtropical-warm temperate belts.The spatial structure of the forest/potential foods under the moist condition was very complex in three dimensions.Both the climate and vegetation changed sharply with the elevation.Accordingly,the former results of ecoethological studies on the animals could be better understood.Foodens (1982) model regarding the ecogeographic segregation of macaques was partly confirmed,but the dichotomy of EB and non-EB macaque habitats was questionable at this site.
