摘要: 目的:观察江宁农田褐家鼠13年的种群数量变化动态。方法:鼠夹捕鼠,计算捕获率;解剖观察怀孕率及胎指数。结果:1985~1997年褐家鼠种群数量变化呈马鞍形,其中1985~1987年捕获率在1%以上;1988~1993年为低谷期,最低为0.17%;1994年起逐年回升,1996年达3.9%,为历史最高年份。结论:褐家鼠种群数量呈回升态势。

Abstract: The population dynamics of Rattus norvegicus from 1985 to 1997 was saddleshaped.From 1985 to 1987,the capture rate was higher than 1% per year,from 1988 to 1993,the rate was very low,the lowest rate was 0.17%,and since 1994,the rate was increasing,and it was up to 3.9% in 1996.The increasing population of R.norvegicus will do much more serious damage to both fields and houses in the countryside.
