Abstract: Objective: It is discussing that the parasitic fleas of surface of Meriones unguiculatus sampling method. Method: It is grounds with different odserve places' mouses amounts and surface of mouses parasitic fleas rate.Uses the formula of the oretical sampling quantity of no repeat sample observed unit of rate after correct n=log^-1(p)*〔q²*N/(p*q+Nd) compute comb-examine mouse quantity. Uses analysis of correlation method analyses beteewn relation Meriones unguiculatus surface of bring fiea rate along with ones fieas of index. Results: The specimens of observe places are 28, reality rational sample amount are 4, it is tis 14.29%;expensive ones are 14, it is tis 50.00% and deficient ones 10, it is tis 35.71%. The specimens of ecolgical environment are 40,reality rational sample amount are 2,it is tis 5.00%;expensive ones are 8,it is tis 20.00% and deficient ones 30,it is tis 75.00%. As to specimens of observe places' analysis of correlation Meriones unguiculatus surface of fiea rate and ones fieas of index recult:n'=26,a=0.0481,b=0.0194,r=0.7518,r_0.001=0.588,P<0.001. Conclusion: The sample quantity starts at least from 20 singles for every time examine Meriones unguiculatus amounts. Meriones unguiculatus' surface of fieas of index along with ones bring fiea rate appear positive correletion change.
