Abstract: The food hoarded by Meriones unguiculatus in the barns with three kinds of habitats in Erdosi desert-grasslands were investigated in the period of Nov. 1~10th, 1989. The results showed:(1)96% of the food composition in their barns were Corispermum seeds, Tribulus terrestris seeds and Bassia dasyphylla ;(2)The annual seed plants of Chenopodiacase was favorite food of M. uniguiculatus. There were dense population of M. uniguiculatus and more barns and food stocked in habitat Ⅰ.(3)The correlation between the population of M. uniguiculatus and its barn numbers was positive(P<0.001), the regression equation was(barn number)=0.3443+0.1228(density of M. uniguiculatus);and(4)There were no significant difference of the barn volumns among three kind habitats(P>0.10).
