全国部分城乡家鼠鼠情监测三年结果分析——Ⅲ.鼠密度的季节性变动

An Analysis of the Results of A Three Year Monitoring Program of Commensal Rodent Infestation in Some Cities and Some Rural Areas of China.Ⅲ.TheSeasonal Population Fluctuation of Commensal Rodents

监测结果及其分析表明,城乡家鼠季节性数量变动曲线的波形基本相似,即城乡两种生态环境对家鼠的季节性数量变动无明显影响;三种家鼠(褐家鼠、小家鼠、黄胸鼠)的季节性数量变动曲线虽有一些差异甚至特点,但受外界环境因素影响很大,不足以成为互相区别的可靠标志;通过对褐家鼠和小家鼠的分析还表明,以动物地理区划为代表的自然生态条件不是影响家鼠季节性数量变动的主要或重要因素,二者之间无明显关系存在。本文采用的“同步起伏分析法”,对于具有复杂波形的鼠类季节性数量变动曲线的相似性分析,可获得明确的结果。

The results of this program, and the analysis on them show that the Seasonal popalation fluctuation carves of the Commensal rodents in the city and the countryside are similar basically inwave shape, which suggests that in the two ecological conditions, that of the city and that of the countryside, do not produce markedly different influences on the seasonal population fluctuation of the commensal rodent, Of the three leading species(Rattus norvegicus, Mus musculus and Rattus flavipectas) although there are some differences or even some characteristic between their seasonal population fluctuations, they are not enough to become the reliable marks to distinguish them from each other because of being affected So much by. outside environment factors. Also the analysis based on the Norway rats and the house mice shows that the natural ecological Condition of the faunae (Zoogeographical divisions)is not the factor which have a great or important influence upon the sensonal population fluctuati of domestic rodents, in other words, there is no notable relationship between the two. The 'Synehro-undulation analytical method' adopted in the present paper can give a definite result for the similarity analysis of the Seasonal population fluctuation Curves of rodents when they have complex wave shapes.
