Abstract: The contents of Cu，Mn，Zn，Fe，Ca and Mg in the liver of Ochotona curzoniae and Myospalax baileyi were studied during April to October，1986．The elements in these solutions were determined by means of atomic absorption spectrophotometer．The specimens were obtained from Haibei Research Station of Aipine Meadow Ecosystem，
Academia Sinica .The main results are as follows：
1．The average contents of trace element in the 1iver of females and males of O．curzoniae has been shown in Table 1．
For females of O．curzoniae the liver contents of Cu，M n，Zn， Fe，Ca and Mg were significantly different among 3 periods，and for males，only Zn，Fe and Mg were found significantly dlfferent．
The trace element contents in the liver were found significantly dlfferent in diffefences sexes except withering period．
2．The average contents of trace element in the liver of M ．baileyi were shown in Table 2．
The contents of Mn，Zn，Ca and Mg in the liver of M ．baileyi were significantly different among 3 periods．
The significant difference of trace element have not been found betweensexs in M ．baileyi．
3．In general，the contents of trace element of M ．baileyi males are higher than females．
4．The contents of total trace element of O．curzoniae are higher than M ．baileyi．
