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 results showed that the above characteristics of Apodemus agrarius were slightly different with the seasons; the foods with carbohydrates were preferred; the average The ratio (?) Was 1: 1.2850. In the spring and autumn of the breeding season, the majority of the sub-adults and adults showed an increasing population. Two peaks of spring and autumn were formed in a year, and the spring peak was higher than the autumn peak. The instantaneous growth rate is: r = 0.6746.
