Abstract: The contents and distributions of the inorganicm acroelements K, N a, Ca, M g, P and A l in skeletons of plateau zoker (Myospalax baileyi) and plateau pika (Ochotona curzoiae) were studied in the area of Haibei Research Station of Alpine Meadow Ecosystem. The result sare as follows: 　　The contents of Ca, P and A l in skeleton of plateau zoker are very significantly higher than that in skeleton of plateau pika (P <0.01) , the contents of Kin skeleton of plateau zoker are extremely significantly lower than that in skeleton of plateau pika (P< 0.001) , and the contents of Na and Mg between plateau zoker and plateau pika are not different (P > 0.05). 　　The distributions of total amount of macroelements in different parts of skeleton are: plateau zoker leg bone> head bone> backbone, plateau pika head bone> leg bone>backbone. 　　In total 15 element pairs, 10 pairs for plateau zoker and 13 pairs for plateau pika are significantly correlated.
