摘要
采用体重与体长的比值作为胴体重长指标KWL',对贵州省余庆县2003～2004年捕获的326只黑线姬鼠(其中,雌鼠160只,雄鼠166只)进行分析研究,结果表明:黑线姬鼠胴体重长指标在1.31～3.25,平均为2.09±0.38, 雌雄鼠胴体重长指标之间无显著差异;不同年龄组之间胴体重长指标差异极显著,且随着种群内年龄的增长,胴体重长指标逐渐增加;不同生境胴体重长指标差异显著;不同月份之间胴体重长指标具有一定差异,在4～5月和8～9月出现2个高峰期,其季节变化趋势为春季最高,夏季较高,秋季较低,冬季最低.黑线姬鼠胴体重长指标与种群繁殖密切相关.
The carcass weight/length index of brands voles was calculated according to an empirical formula by measuring 326 samples of Apodemus agrarius （160 females and 166 males） caught in Yuqing county of Guizhou in 2003 - 2004. The results indicated that the carcass weight/length index was 2.9±0.38 in average, There were no significant difference in carcass weight/length index hetween females and males,but it revealed most significant difference among the different age groups and increased in accord with the increasing of age. The various circumstance caused the significant different index,and also varied with the seasonal change in order of spring〉summer〉autumn〉winter.
