Abstract: The contents and distributions of 12 trace elements were analyzed in the wholelength bone, cranium , backbone and legbone of plateau zoker (Myospalax baileyi) and plateau pika (Ochotona curzoniae). The twelve trace elements are Cu, Zn, Fe, M n, Co,N i, Mo, Cr, F, Se, T i and Ge. The results were as follows: 　　The difference of the contents of only Cu in the skeleton of two kinds animals was not significant, the difference of another 11 trace elements were remarkable (P< 0.05 or P < 0.01) , the contents of Zn, Fe, M n, Co, N i, Mo, F and Se of the plateau zokers were higher than the plateau pikas; Cr, Ti and Ge of the plateau pikas were higher than plateau zokers. 　　The distribution of trace elements was not average in the cranium , backbone and leg bone, the trace elements were the richest in the cranium.
