198 7～ 1 998年在东莞市稻、果、菜混种区研究了黄毛鼠种群的繁殖动态。结果表明 ,黄毛鼠在 1 2月和 1月很少繁殖 ,2～ 1 1月是正常繁殖期 ,3～ 1 0月为繁殖盛期 ,每年有 2个繁殖高峰期 ;繁殖指数是衡量害鼠繁殖力强弱的综合指标 ,其季节变动大而年间变动小 ,因而导致黄毛鼠种群数量的季节变动很大 ,而年间数量变动较平稳 198 7 ~ 1 988 in Dongguan City, rice, fruit, vegetable mixed areas of rapeseed population breeding dynamics. The results showed that the rodents rarely breed in January and January, the normal breeding period from January to January, the breeding period from March to October, and the peak of breeding season in each year. The reproductive index is the measure of harm The comprehensive index of the fertility of the rats, the seasonal variation is large and the variation is small during the year, which results in a great seasonal change in the population of the rodent, while the quantity changes more smoothly during the year
