Abstract: Investigations on small mammal community in crop fields of western and southern
plains in Shandong province were carried out from M arch,1 992to M arch,1993. Six communities were classified as follows:
A. Flood land field Cricetulus barabensls community;
B. Flood land field near residential area C. barabensis+ Mus musculus community;
C. Gentle Sloping field C. barabensis+ Apodesnus agrarius community;
D. Shallow flat low—lying fieId A.agrarius+ C.burabensis+ c.triton community.
E. Low—lying field C. barabensis+ A. agrarius+ C.triton community;
F. Low—lying vegetable plot A . agrarius+ C. barabensis com m unity.
Seasonal changes in comm unity com pisition w ere distinct except in community A .From Novemher to February in next year C. barubensis was the dominant,in other months was A. agrarius or C. triton,Seasonal migrations of house mouse (musculus)were also f0und in crop field near residentia1 area.

摘要: 作者于1992年3月至1993年3月在鲁西和鲁南平原农作区对小型兽类群落进行了调查,其群落组成以啮齿动物为主.可划分为6类群落:河滩高地的黑线仓鼠群落,河滩高地人房附近的黑线仓鼠+小家鼠群落,缓平坡地的黑线仓鼠+黑线姬鼠群落,浅平洼地的黑线姬鼠+黑线仓鼠+大仓鼠群落,洼地农作区的黑线仓鼠+黑线姬鼠+大仓鼠群落和洼地蔬菜种植区的黑线姬鼠+黑线仓鼠群落。群落的季节变化明显,11月至次年2月以黑线仓鼠为优势种,其它月份则黑线姬鼠或大仓鼠较多;人房附近农作区小家鼠也有季节性迁移现象。
