摘要: 本文论述了金华北山啮齿类的区系组成、数量季节消长和垂直分布。依据不同生境中鼠种和数量的组成,划分了7个鼠类群落。进而对比和分析了各鼠类群落的组成和空间配置、多样性及生物量的分配。通过以人工针叶林为主的北山与具良好次生林植被的天目山自然保护区之间的比较,表明鼠类组成方面有着明显的差异,并探讨了造成这种差异的部分原因。

Abstract: The ecological study of rodents in Jinhua Beishan Mountain was carried out from February 1984 to January 1985. Three working sites were set up at different altitudes in the mountain range. Results obtained are as follows.1. Eight species of rodents were captured in seven different ecological habitats. Apodemus agrarius and Rattus niviventer confucianus are dominant species.2. There is seasonal change of numbers. Peaks in the fluctuation curve appear in March,June-August and October-November respectively.Species diversity indexes,relative densities and species are different in every working site.
