【摘要】 目的　了解广州市各环境的鼠类群落结构特征 ,为鼠害控制提供依据。方法　对各种环境现场调查的鼠情进行分析及数量统计。结果　有效控制前 ,广州市鼠类群落结构为褐家鼠 >黄胸鼠 >小家鼠。随着对鼠害控制工作深入开展 ,鼠类群落结构演变成黄胸鼠 >褐家鼠 >小家鼠和小家鼠 >褐家鼠 >黄胸鼠等不同的结构类型。结论　褐家鼠为广州市家栖鼠中的主要优势种群 ,是鼠害控制工作的重点对象。对于具有天花板及夹层结构的建筑物 ,要加强对黄胸鼠的控制工作。在较长时期有效控制鼠害后 ,特别在物流频繁的仓储类环境中 ,要注意加强对小家鼠的监控。更多还原

【Abstract】 Objective To study the Characteristics of community structure of rodents at different habitats in Guangzhou,provide scientific basis for rodent control. Methods To investigate the species and density of rodents in different habitats in Guangzhou city. Results Before control,the community structure of rodents was R.norvegicus> R.flavipectus> M.musculus . After taking effective control for a long time,some community structures had been changed into R.flavipectus>R.norvegicus>M.musculus or M.musculus>R.norvegicus>R.flavipectus . Conclusion R.norvegicus was the major species which would be controlled in urban environment.It is important to control R.flavipectus in the buildings with ceiling and double-layered structures. After taking effective control for a long time,it is necessary to streng the surveillance and control on M.musculus in the storehouse where goods were frequently moved.更多还原
