| 摘 要： | 黄胸鼠种群数量发生动态分析结果可以为该鼠的预测预报及防治提供依据。本文分析了1986-2015年间贵州省息烽县黄胸鼠种群数量调查数据,总结了其季节性及年际种群数量动态。结果发现,在息烽县,黄胸鼠主要栖息于住宅区,作物区仅有零星分布。期间共捕获黄胸鼠938只,总捕获率为1.07%,住宅区黄胸鼠占总捕获鼠数的15.20%,不同年度间其群落占比为1.14%~32.49%,变化差异极显著。从季节性捕获率看,种群数量夏季(6~8月)最高,总平均捕获率为1.32%,其中7月捕获率为1.55%,是全年最高点。冬季(12月至翌年2月)最低,总平均捕获率为0.66%,其中1月数量最低,平均捕获率为0.49%。

| Abstract: | Analysis of population dynamics of Rattus flavipectus can provide evidence for its forecasting and management.We analysed the monitoring data of Rattus flavipectus in Xifeng County from 1986 to 2015 and assessed the monthly and annual variations in the population size.The results showed that Rattus flavipectus was mainly trapped in the residential area,seldom in the crop area.A total of 938 Rattus flavipectus were trapped during this period from the total of 87633 snap-traps,accounting for 1.07％ of successful trapping.It should be noted that four other rodent species were also trapped.The percentage of captured Rattus flavipectus was 15.20％ in all rodent species trapped in the residential area.There were significant differences of the annual population proportions of Rattusflavipectus among the all captured rodents,varied between 1.14％～32.49％.Seasonal population variation showed a single-peak type and the highest number occurred in summer (from June to August).The average yearly trap rate was 1.32％,with the highest trap rate of 1.55％ in July and the lower trap rate of 0.66％ in winter (from December to January),and the lowest trap rate of 0.49％ in January. |
