摘    要:本文报道卡氏大鼠种群数量变动特征及其与环境因子的关系,种群数量年间变动较大,季节较化一般出现2个高峰。分别在5-6月和11月,与农作物的成熟,收获以及小鼠繁殖活动有关,1月份的种群数量多及2、3月份的平均气温高低,对当年5月份种群数量有密切关系。本文提出了3个回归方程式,可初步估计当年5月的种群数量。

关 键 词:卡氏小鼠  种群变动  环境因子  鼠害

Abstract:This paper deals with the population fluctuation characteristics and relations toenvironmental factors in Mus caroli,an important rodent pest of crops.Trapping wasmonthly conducted in cultivated land in Tonghai County,Yunnan Province fromJanuary of 1990 to September of 1993.A tatol of 15 811 trap-days captured 1027rodents,in which Mus caroli accounted for 76.14%.Significant differences of average of monthly population numbers between differentyears were found.The population fluctuation usually peaked twice a year,i.e. duringMay to June and in November.The density fluctuation seems to be related todevelopmental stages of crops and also reproductive activities of animals.The population numbers in May related closely to the average of monthly meantemperature during February to March and to the population numbers in January. Twolinear and one multiple linear regressions were run of estimated the population numbersin May of the year.
Keywords:Mus caroli  Population fluctuation  Environmental factors
