摘　　要：通过对果洛州草地害鼠现状及其对草地危害的调查以及历年来灭鼠情况的分析,结果表明造成果洛州鼠害长期得不到控制的主要原因:(1)采用化学药剂防治害鼠导致天敌死亡;(2)草场退化造成鼠害大面积发生;(3)经济利益驱动导致鼠类天敌被捕杀,害鼠天敌逐年减少;(4)气候变暖使鼠害繁殖特性发生变化。因此,对果洛州今后害鼠防治提出如下建议:(1)生物防治是主要防治措施;(2)巩固、扫残是有效控制害鼠的重要保证;(3)生物生态防治是长期、彻底控制害鼠的有效手段。Investigation of mouse situation and damage to grassland and analysis on exterminating mouse had been conducted in Guoluo prefecture.
