摘要
上海郊区农田主要鼠形小兽有黑线姬鼠和大麝鼩。1988～1989年在郊区嘉定县农田以夹夜法调查,发现农田鼠形小兽群落结构发生了很大变化,与60年代初相比,大麝鼩的构成比从17%上升到80%左右,黑线姬鼠则从80%以上下降到20%左右,这可能与近年来郊区农田开展经常性灭鼠工作有关。
By investigating the densities of mouse-like mammals in Shanghai suburb from 1988～1989, it is found that the proportions of C. lasiura in community ascent from 17% in 1960's to about 80% in 1980's and the proportions of A. agrarius descent from 80% in 1960's to aboat 200% in 1980's. This is perhaps caused by frequent rodent control campaign in the agricultural fields of Shanghai suburb in recent years.
