摘要
本文对福建家鼠组成比进行了调查研究,并与50年代进行了比较,证明已有明显的变化,褐家鼠已成为优势种。对福建南部和北部家鼠组成上也进行了比较,闽北褐家鼠比闽南多52.50%,闽南臭鼩鼱比闽北多2.62倍。福建家鼠和田园鼠一年有两个季节高峰,前者在4月和10月,后者在4月和9月。
The studies on species composition proportions and population seasonal differences of rolents in Fujian in 1990. The results obtained are as follows.1. The composition proportions of domestic rolents in Fujiart are R. norvegicus 52.12%, R. flavipectus 24.15%, Mus musculus 6.90%, Suncus marinas (Insectivora) 16.80%. The composition proportionsin 1990, as compare with that in 1980 have distinct differences, from the second place goingup to the first for R. norvegicus.2. The composition proportions of domestic rodents in the south was compare that in the north of Fujian have distinct differences. The number of R. norvegieus is higher in the north thau the outh. The number of Suncus murinus is higher in the South than the north.3. The peak of seasonal population density for domestic rodents are April and October, field rodents are April and September.
