Abstract:Majiashan Nature Reserve (MNR; 105º28’105 º 40’E, 32 º50’32 º56’N) is geographically located on the southern slope of the western range of the Mt. Qinling is Shaanxi Province of China. The transect survey and visiting investigation were carried out in the MNR to study the resource, fauna and ecological distribution of large and medium-sized mammals (primates, carnivore and artiodactyl) from October to November, 2004. In MNR, there are 23 large and medium-sized mammals, five and nine of which respectively belong to the first and second class state key protected wildlife in China. It is one of key regions for protecting the species diversity of Mt. Qinling. Golden monkey (Rhinopithecus roxellana), rhesus macaque (Macaca mulatta), giant panda (Ailuropoda melanoleuca), takin (Budorcas taxicolor tibetana) distribute together in the field, and the MNR is a new distributing region of the four rare and endangered species. Among the 23 mammals, there are 17 oriental species (73.9%) and 6 widely-distributed species (26.1%). The results of analyzing the ecological distribution of the 23 mammals show that there are 16, 20 and 12 species in the mixed evergreen and deciduous broadleaf forest, the broadleaf deciduous forest, the mixed coniferous forest respecitively. The vertival distributed amplitudes of these species have large differences. The mammals whose vertical distributed elevation scopes are above 1000m , 5001000m and below 500 m have 5, 13 and 5 species respectively. The number of the species on the different elevation strips in the MNR changes stably with elevation ascent, and does not show the regularly vertical change with evident ascent or descent.
