【摘要】 为了掌握黄胸鼠(Rattus flavipectus)在山西省的分布现状,为种群数量预测预报和制定相应的防治措施提供科学依据,在11个地市的15个县(市、区)采用夹(笼)捕法对其进行了调查,并采用体质量法研究了黄胸鼠种群的年龄结构。结果显示,黄胸鼠在山西省的8个地市有不同程度分布,并且有继续北扩的趋势;黄胸鼠成年组(Ⅲ)和老年组(Ⅳ)的群体数量占到54.28%。表明黄胸鼠种群有形成数量高峰的可能,需密切监测其数量动态。更多还原

【Abstract】 To master the distribution status of Rattus flavipectus in Shanxi province,and to provide scientific basis for population forecasting and control measures,in the paper,15 counties(cities and districts)in 11 cities were investigated by snap(cage)method,and the age structure of Rattus flavipectus population was studied by quality method.The results showed that the 8 cities of Shanxi were distributed,and there was the tendency to expand the north in Shanxi about Rattus flavipectus.The population of the adult group(III)and the old group(Ⅳ)accounted for 54.28%,which indicated that the population was probably to form the peak quantity,and the quantitative dynamics of the population should be closely monitored.更多还原
