【摘要】 1984年3月—1985年1月对闽东山区鼠类群落的调查结果表明,根据鼠种类和数量组成,该区可划分为针毛鼠+社鼠;黑线姬鼠+黄毛鼠、黄毛鼠+黑线姬鼠;褐家鼠+小家鼠+黄胸鼠等4个鼠类群落。不同鼠类群落的组成和数量有不同的季节变化。本文比较了不同鼠类群落的多样性指数、均匀性指数和相对生物量。更多还原

【Abstract】 The space disposition and structure of rodent communities in East Fujian mountainous area were investigated in Zhouning county from Mar. 1984 to Jan. 1985. Results are as follows: 1. The space disposition of rodents from residential district to forests of mountainous country is in the order of Rattus norvegicus, Mus musculus, R. flavipectus, Mus formosanus, R. rattoides, Apodemus agrarius, R. niviventer, R. fulvescens and R. bo-wersi.2. According to the data obtained the rodents in Zhouning county can be devided into four communities a: A, R. fulvescens + R. niviventer community. B, A. agrarius + R. rattoides community. C, R. rattoides + A. agrarius community. D, R. norvegicus + Mus musculus + R. flavipectus community.3. There are seasonal variations of composition in different communities.4. There are different species diversity indices in different communities. The highest diversity index has been found in community C (Community A lacks data in all year).5. The rodential biomass in different communities is different,and the highest bi-omass of the field has been shown in community C. The biomass of community D in residential district is higher than that of communities in the field.更多还原
