云南盈江县鼠疫宿主动物种群分布和季节消长分析

目的掌握盈江县鼠类种群分布及季节消长规律。方法整理和分析鼠疫监测和疫情资料。结果该地室外黄胸鼠构成比呈明显上升趋势,而其它鼠种构成比则逐渐降低,黄胸鼠在种群上占有绝对优势,室内总鼠密度和黄胸鼠密度年度变化基本一致;黄胸鼠密度与总鼠密度季节消长趋势基本吻合,室外总鼠密度明显高于室内,室内总鼠密度和室内外黄胸鼠密度季节变化不明显,全年保持相对稳定。结论根据鼠类年度变化和季节消长规律,保持鼠疫联防工作的连续性,适时开展灭鼠活动,把鼠密度维持在一个较低的水平,降低鼠疫暴发流行的机会。

Analyzing on the Population Distribution and Seasonal Variation of Plague Host Animal in Yingjiang county, Yunnan.

Objective To know the population distribution of rodents and their seasonal variation in Yingjiang county.Methods Collect and analyze the surveillance data and the epidemic data of plague.Results Constituent ratio of Rattus flavipectus show obviously to be up tendency,but other rodents decreased gradually,Rattus flavipectus has absolutely dominance in the whole rodents population.Annual variation of indoor density between the whole rodents and Rattus flavipectus were with the accord,the same of season variation tendency betwee 年 Rattus flavipectus density and the whole rodents density,Outside density of the whole rodents was obviously more high than inside.There are not obviously change about seasons variation tendency which of the whole rodents density was inside and Rattus flavipectus density was outside and inside.Conclusion Based on regular pattern between the construction of rodents population and their seasonal variation,we should keep on taking united measures which are made use of plague control and prevention.
