The population dynamics and the numbers prediction of striped hamster (Cricetulus barabensis) have been stuied in Huhehot from 1984-1991. The results obtained are as follows.1. The regression equation of reproductive indices within one year is:I(t) = 0. 8371 + 0. 7602t-0. 0661t2,r=0. 4611,F = 4. 7262>F<0.05(1.35) = 4. 14,where I(t) represents the reproductive indices in month t.2. The regression equation of capture rates for months is:Nt+1 = 0. 8904 + 0. 0421 Nt+ 0. 0904Mt2,r = 0. 9439,F=126. 59>F0.01(1.31)...
