摘　　要：本文研究了黑线姬鼠的食性,性比,年龄结构、季节消长规律及种群增长模型.结果表明,黑线姬鼠的上述特征随季节略有差异;喜食含碳水化合物的食物;平均性比(?)为1:1.2850;在繁殖季节的春秋两季,亚成体和成体居多,种群呈增长型;一年之中形成春秋两个数量高峰,春峰高于秋峰;该鼠种群的瞬时增长率为:r=0.6746.The population character and population dynamics of Apodemus agrarius pallas including food, sexual rate of the population,age structure,Population size with vatied seasons and population growth form have been conducted. The results showed that the character of the biology and ecology features changed with seasons: it prefered to feed the food of contenting higher carbohydrate, the average sexual rate between female and male in a year was l:1.2850; The number of subadult and adult individuals in reproductive seasons of spring and autumn was more than other seasons , and the population size presented growth from two peaks of population size presented in spring and autumn respectively, which the spring was much higher than the autumn from Sichuan Province.The Populatin instantaneous growth rate was r = 0.6716.
