摘　　要：对2000-2008年贵州省余庆县捕获的51只黑腹绒鼠(雌鼠21只,雄鼠30只)肥满度和胴体重长指标进行了分析,结果表明:黑腹绒鼠平均肥满度和胴体重长指标分别为(3.03±0.06)g/cm3、(2.05±0.05)g/cm,雌雄鼠之间差异均不显著;不同年龄组之间肥满度差别不大,胴体重长指标具有极显著差异,且随种群年龄的增长,胴体重长指标不断增加;肥满度的季节变化趋势为秋季>春季>冬季>夏季,季节性差异不显著;胴体重长指标的季节变化趋势为春季>秋季>夏季>冬季,季节性差异显著。From 2000 to 2008,51 Eothenornys rnelanogaster were captured in Yuqing county, Guizhou province,among which 21 were female and 30 were male. The captured specimens were brought baek to laboratory to measure for relative fatness and body weight/length without viscera index. The relative fatness and body weight/length without viscera index were （3.03±0.06） g/cm^3 and （2.05±0.05） g/cm respectively. The results show that there is a significant variation between the male and the female, and an insignificant variation among different age groups in the relative fatness. It is significant variation in body weight/length without viscera index among different age groups. The body weight/length without viscera index is inereased with age rise. The relative fatness varies insignificantly by season and the change trend is autumn〉spring〉winter. summer. The body weight/length without viscera index varied significantly by season and the change trend is spring, autumn 〉 summer〉 winter.
