摘要
采用K—100W／L^3作为肥满度指标，对贵州省三都县1997～1999年捕获的405只黄胸鼠肥满度进行分析研究，结果表明：黄胸鼠平均肥满度为3．31±0．75．两性间肥满度差异不显著，不同年龄组之间肥满度差异显著。肥满度的季节变化趋势为：夏季最高，其次为春季和冬季，秋季最低。不同月份之间肥满度存在一定差异，不同年度之间差异极显著。
The relative fatness of 450 Rattus flavipectus was analyzed by using the empirical formula K： 100W/L^3. The results show that the mean relative fatness is 3.31±0.75, there is a significant difference between different age groups and no significant difference between female and male in relative fatness. The relative fatness varies with the seasonal change and the change trend is summer〉 spring〉 winter 〉 autumn, and there is a difference between different months and a significant difference between different years in relative fatness.
