| 摘 要： | 四川盆地连续３年农业生态系统害鼠种数量的统计分析表明，种群数量在年际间变化不显著，而年内存在着显著的统计学差异。种群数量季节消长呈明显的双峰模式，年周期内出现６月和１１月两个数量高峰，两峰之间无显著性差异。

| Abstract: | The rodent pest density of the agricultural system was recorded for three years in Sichuan , the results showed that the fluctuation of the population density in different years is not significantly different (the analysis of variance, FF0.05) The seasonal population density had two peaks, which occurred in Jun. and Nov. , and the two peak values are not significant different (t
