Abstract: Objective:To investigate on field rats population variation,distribution and it's relation with HFRS.Methods:Mousetrap capture.Results:The field rats density was 2.31% in HFRS area.The dominant species was Apodemus agrarius and Crocidura lasiura.The population peak of rats was on May-July.The HFRS peak was on June-August.So there was a better relation ship between population peak of rats and HFRS peak.The Apodemus agrarius and Crocidura lasiura were distriuted extensively in field,but the main places of stay were river bank,water ditch,around the dwelling and rice field.The disorderly dirty could influence the density of rats.Conclusion:The field rats control must be strengthen in HFRS area.The time of field rats control should be May and winter.Above-mentioned places should be the main places being carried out control measures.

摘要： 目的:了解肾综合征出血热(HFRS)地区农田鼠逐月数量变动、分布以及与发病的关系。方法:鼠夹法。结果:农田鼠密度为2.31%,以黑线姬鼠、大麝鼩为绝对优势种,全年出现5～7月数量高峰,与HFRS发病高峰6～8月相吻合。黑线姬鼠、大麝鼩在室外分布广泛,但以河边沟渠、宅周、稻田为主;环境零乱、垃圾众多会影响鼠形动物密度。结论:控制野鼠性HFRS,应强化室外农田灭鼠,适宜时间为5月和冬季。
