Structure and Quality Evaluation of Rangeland Resources of Xizang (Tibet) Autonomous Region

Su Daxue (Commission for Integrated Survey of Natural Resources, Chinese Academy of Sciences, Beijing 100101)  
There are about 82 million hectares of various rangelands in Xizang (Tibet), accounting for one fifth of the total grassland area in China, is 23o times of its cultivated land and 11 times of different kinds of woodland and shrubland. The main component of range in Xizang is alpine rangeland distributed in the sub -frigid and frigid zones, composed of small sedge and short grasses, and used as grazing rangeland only. The forage yield of the Xizang range is the lowest and the area of hardly to be used is the largest in China. But there is no mowing grassland in Xizang. The area of grazing range for clod season is small, but the using period is long and the carrying capacity is low too. The warm season range is large in area and the using period is short. The unbalanced carrying capacity is the main limited factor for the development of animal husbadry productivity in Xizang.
