摘要
1987～1989年,在莆田地区农村逐月对家鼠种群进行调查,布放14400笼日,捕鼠2841只,捕获率为19.73%。捕获鼠4种,小家鼠占总数的56.88%,但其组成比有一定的季节变化;有的月份(如8月),褐家鼠数量可接近或超过小家鼠;黄胸鼠为常见种,冬季的组成比较高;黄毛鼠在5月和12月前后偶尔窜入室内。通过相关分析,小家鼠与黄胸鼠、褐家鼠种群数量间相关非常显著或显著,而褐家鼠和黄胸鼠种群数量无相关性。比较50～80年代调查资料,发现家鼠群落处于不断变化中,群落优势种的演替趋势是:黄胸鼠→褐家鼠→小家鼠。
1. Thiswook was carried out in Putian county, from Mar. 1987 to Feb. 1989. 2841 specimens were collected. Average capture rase was 19.73%. 2. There are four species in house rodents. Mus musclus was dominant species of house rodents, being 56.88% of the whole house rodents. There are obvious seasonal variations of specific composition in house rodents. 3. Using regression analysis, the positive correlations between the population denslty of Mus musculus and Rattus flavipectus (r=0.518>r0.01, n=24), Mus musculus and Ruttus norvegicus (r=0.408>r0.05, n=24) were disocverred, and there was no correlation between the population density of R. norvegicus and R. flavipectus(r=0.081>r0.05). 4. There was obvious succession of house rodents community from 1950s to 1980s. The dominant species of community were R. flavipectus, R, norvegicus and Mus musculus in turn.
