摘　　要：为掌握农区褐家鼠不同年龄组、不同性别、不同季节、不同生境形态特征的变化规律,对贵州省播州区2016—2022年捕获的195只褐家鼠不同年龄组、不同性别、不同季节、不同生境的形态特征进行统计分析。结果表明:褐家鼠体重平均为(88.96±42.11)g,胴体重平均为(65.47±30.32)g,体长平均为(143.57±28.05)mm,尾长平均为(109.06±28.70)mm,后足长平均为(29.38±4.73)mm,耳高平均为(13.67±2.55)mm。不同性别形态特征差异不显著;不同年龄组之间体重、胴体重、体长、尾长、后足长、耳高随着年龄的增长而不断增加;不同季节形态特征有一定变化;农田区各项形态指标均高于住宅区,差异不显著。In order to master the changing law of the morphological characteristics of Rattus norvegicus in different age groups,sexes,seasons and habitats in agricultural areas,the morphological characteristics of 195 R.norvegicus captured in Bozhou district of Guizhou province from 2016 to 2022 were statistically analyzed.The results showed that the average body weight of R.norvegicus was(88.96±42.11)g,the average carcass weight was(65.47±30.32)g,the average body length was(143.57±28.05)mm,the average tail length was(109.06±28.70)mm,the average hind foot length was(29.38±4.73)mm,and the ear height was(13.67±2.55)mm.Body weight,carcass weight,body length,tail length,hind foot length and ear height of R.norvegicus increased with age,and there was no significant difference in morphological characteristics of different sexes.The morphological characteristics of different seasons had certain changes;All morphological indexes in farmland area were higher than those in residential area,but no significant difference was found in the those indexes collected from farmland area and residential area.
