作者于1995年～1997年对鲁中南丘陵地区农田鼠类种群密度消长规律及繁殖特征进行了研究,结果表明当地农田鼠类共6种,黑线姬鼠为优势鼠种,大仓鼠为常见鼠种;鼠总密度变化呈双峰型,前峰在7月,后峰在10月,前峰略高于后峰。黑线姬鼠密度变化与鼠总密度变化类似,即7月和10月各有一个数量高峰,但峰度为后峰高于前峰;大仓鼠仅有1个密度高峰在7月。黑线姬鼠繁殖期在3～10月间,在5月和9月各有一个繁殖高峰,平均胎仔数5.05个;大仓鼠繁殖期在4～9月间,仅有1个繁殖高峰在5月,平均胎仔数为9.44个。
The authors studied the growth and reproduction characteristics of farmland rodents density in the hilly areas of Central and Southern Lhasa from 1995 to 1997. The results showed that there were 6 species of rodents on the farmland and the dominant species were Apodemus agrarius, Species; total density of rats showed bimodal type, the former peak in July, the latter peak in October, before the peak slightly higher than the latter peak. The density change of Apodemus agrarius was similar to the change of total rat density, that is, there was a number of peaks in July and October, but the kurtosis was the posterior peak higher than the anterior peak; only 1 density peak of the large hamster was in July. Apodemus agrarius breeding season in March to October, in May and September each have a breeding peak, the average number of litter 5.05; large hamster breeding period from April to September, only one breeding peak in 5 Month, the average number of litter 9.44.
