对洞庭湖滨湖丘岗地的鼠类群落结构和生物多样性变化进行了研究.共置鼠夹2 437夹夜
捕鼠7种
共417个个体.结果表明两个时间段捕获的鼠种数不同
分别为7种和5种
捕获率分别为(12.29±7.05)%和(3.05±1.44)%(t=4.26

但均匀性指数差异显著(t=5.433

将所有年份的群落相似性指数聚类为2类
即1992

已经成为完全不同的群落.
Succession of rodent community was studied between two periods 1992 to 1995 and 2002 to 2004 in the woodland of hill in Dongting Lakefront.A total of 417 specimens from 7 species of rodent(Microtus fortis
Apodemus agrarius
Rattus norvegicus
Rattus flavipectus
Niviventer confucianus
Rattus losea
Micromys minutus) were caught by traps.There were 7 species of rodent in 1992 to 1995 and 5 species in 2002 to 2004.Capture rates of rodent had significant differences((12.29±7.05)% and(3.05±(1.44))%
t=4.26
p<0.001
df=21) and the dominant species were different between 1992 to 1995 and 2002 to 2004.M.fortis(50.49%) and A.agrarius(33.88%) were the dominant species in 1992 to 1995 and N.confucianus(65.45%) and A.agrarius(23.64%) were the dominant species in 2002 to 2004.The diversity index and dominance index had not significant differences in different years
but evenness index had significant differences.Based on similarity index of six years
it could be categorized into two groups with systematic clustering: 1992 to 1994 and 2002 to 2004.We conclude that
in the woodland of hill in Dongting lakefront
the rodent community had been changing a different one after ten years.
