摘　　要：农田鼠类和类动物随季节、作物布局和环境而不同,其栖息地也随之发生变化。研究表明,农田鼠类有向院落集中,向粮食地集中分布的特点,但趋性的强弱随鼠种和时间而异。大足鼠、褐家鼠向院落集中的趋势强于其它小型鼠种。一般而言,12月～次年2月院落周围的鼠密度高;3～6月和9～10月以麦田、稻田的鼠密度最高。田间鼠密度按粮食地>蔬菜地>果园>经作地>荒地>秃地的顺序递减。栖息地灭鼠可以减少毒饵用量,降低成本,提高灭效。The distribution of small mammals,rodents and Insectivora in farmlands varied with seasons,distribution of farm plants and environments,and their habitation spaces also changed.The study indicated that rats and mice moved and habitated closely to county yard or grain fields,but the population size near house or grain field varied with seasons and species of rats.Rattus nitidus and R.norvegicus were more closer to houses than other small species in some seasons.Generally,in the period of Dec.to Feb.of the next year,rats population near houses was much higher than that in other monthes.But in the monthes of 3-6 and 9-10,rats lived in wheat fields,rice fields.Rats population size changed as grain field>vagetable field>orchard>economic plant field>uncropped field>bare land.It was effective to control rats and mice in habitation space with decreased baiting dosage and lower cost.
