摘　　要：农田害鼠的种类除与当地的地理环境相适应外,还具有鼠种相对较少,优势种突出,易维持较高数量水平的特征。各鼠种在农田的分布与作物种类有一定的关联度,随着季节变化、作物生长和各种农事活动的干扰,害鼠在作物地之间、或与周围环境之间迁移。随着环境条件的变化,农田鼠类群落不断地进行演替。The rodent communities on farmlands, while adapted to the local environmental conditions, are characterized by comparatively few species and dominated by one or two species with high population level. The distribution of rodents on farmlands were correlated to the crop types and influenced by agricultural structures and activities. It may be because different crops create different microclimates and food resources for different rodent species, whereas different agricultural activities change rodent habitats. So different rodents are adapted to different crop fields, and they migrate between crop fields or between crop fields and surrounding areas. The rodent communities keep succession due to the changes in farmland environments.
