对全国家鼠鼠情监测网一年监测结果的分析表明:城、乡家鼠组成均以三种家鼠为主,但顺序和其他鼠种进入居室的机会有所不同;褐家鼠、小家鼠、黄胸鼠、臭鼩鼱、黑线姬鼠的地区分布均与以往文献记载基本一致;各地鼠密度水平不平衡,有的甚至还相差悬殊,农村鼠密度明显高于城镇,地理位置与鼠密度水平无明显关系;城乡两种生态环境、不同动物地理区划、不同鼠种与家鼠种群数量的季节性波动之间,均未发现明显、稳定、规律性的联系。
The monitoring results of the whole country’s rat and mouse monitoring network showed that there were three kinds of domestic rats in the composition of domestic mice in both urban and rural areas, but the order was different from that of other mouse species entering the home. Rattus norvegicus The geographical distribution of house mouse, Rattus flavipectus, Smelly stinkbug and Apodemus agrarius were basically the same as those in the previous literature. The density of rat was unbalanced in some areas, and some even varied greatly. The density of rat in rural area was significantly higher than that in urban areas and urban areas There was no obvious relationship between the density of the rat and the rat density. There was no obvious, stable and regular relationship between the two ecological environments in urban and rural areas, the geographical division of different animals and the seasonal fluctuation of the numbers of different mouse species and domestic mice.
