摘　　要：本文利用Jolly-Seber法估算了1986和1988年河北省饶阳县大仓鼠和黑线仓鼠的种群大小、存留率等参数。结果表明,大仓鼠的存留率比黑线仓鼠小,而且和密度负相关。大仓鼠和黑线仓鼠对铁丝活捕笼均不存在非等捕性。该方法对大仓鼠和黑线仓鼠种群参数估计是可行的。By using capture-mark-recapture and Jolly-Seber methods, some population parameters of C .triton and C.barabensis in Hebei, China, were estimated in 1986 and 1988.It was found that the'survival rate'(including mortality and dispersal) of C.triton was smaller than that of C. barobensis and negatively related to population density. Both C. triton and C. barabensis showed equal probability of being trapped despite of different times of being trapped before.
