摘  要:
研究将洞庭湖东畔岳阳县麻塘垸稻田、岗地、湖洲与农户住房鼠类群落分为 4种类型 ,A稻田为黑线姬鼠+东方田鼠 +褐家鼠 ,B岗地 (含旱作地 )为东方田鼠 +黑线姬鼠 +黄毛鼠 ,C湖洲 (苔草地 )为东方田鼠 ,D农户住房为小家鼠 +黄胸鼠 +褐家鼠。稻田与岗地 2鼠类群落结构相似 ,且年与年间达显著差异 ,其他群落间结构差异达极显著。岗地鼠类群落多样性指数最高 ,为 1.6 19;湖洲鼠类群落多样性和均匀性指数最低 ,分别为 0 .0 5 2和0 .0 33,但其优势度指数却最高 ,为 0 .990 ;农户住房鼠类群落均匀性指数最高 ,为 0 .72 1,而优势度指数最低 ,为0 .4 0 7。

摘  要:
Rodent communities have been studied in Matangyuan,Yueyang County,Dong ting lakefront rice area.The rodent communities can be divided into four types,i .e. Apodemus agrarius+Microtus fortis community in farmland(A),Microtus fo rtis+ Apodemus agrarius+Rattus rosea community in hills(B),Microtus fortis commu nity i n lake beach(C),Mus musculus +Rattus flavipectus +Rattus norvegicus communit y in indoor(D).The structure of community A is similar to that of community B,and th ey are significantly different between years,but other community structures are significant difference .The diversity index of community B is the highest one(1. 619).The diversity and evenness indexes of community C are the lowest(0.052 and 0.033),but its dominance index is the highest(0.990).Evenness index of community D is the highest(0.721),but its dominance index is the lowest(0.407).
