Nature reserve is a genral concept. Due to different localities and different natural features, there are different objectives and pretection purposes. Each nature reserve will be managed according to certain classification and grade. Obviously, before a nature reserve is chosen and its classification and grade, scientific evaluation for the protection area must be made.The mount Qomolangma Nature Reserve is located in Tibet Autonomous Region of Southwestern China. Its location is approximately between latitudes 27°48'--29°19' N and longitutes 84°27'-88°00'E. The whole area is approximately 33910km2. About 12000 families live in the Reserve with a total population of 67 000 Tibetan people. Administratively the Reserve belongs to the Shigatse Administration's Dingri, Jilong, Nielamu, Dingjie and Saga Counties.The reserve not only has the special regional characteristics of the natural geological units of the south Tibet Plateau and the central Himalaya montane System. At the same time, it also has many rare and endangered wildlife and botanical species that are on the nation's protection list. The Reserve still keeps its naturalness and is very attractive. The ecosystem of the Reserve is very fragile It is in need of protection. The area is so large and diverse that it has tremendous potential for scientific research. According to the above-mentioned reasons, the Mount Qomolangma Nature Reserve should belong to the multidisciplinary type (or the ecological system protection area) and should be classified as a national-level nature reserve.
