近年来由于农田害鼠发生面积不断扩大，导致粮食产量损失严重。为此，笔者于２００１年对稻田害鼠的空间格局及防治指标进行了研究。确定了适合安源区目前农业生产水平的稻田害鼠防治指标：即晚稻孕穗期捕鼠率为５％，黄熟期为７％。１调查与方法１．１空间格局２００１年晚稻 In recent years, due to the growing area of ​​pests in farmland, resulting in serious loss of grain yield. Therefore, in 2001, the author studied the spatial pattern and control index of paddy rat. The control index of paddy field pest rats suitable for the present agricultural production in Anyuan District was determined: the rate of catching rat was 5% at booting stage and 7% at yellow ripe stage. 1 Survey and Methods 1.1 Spatial Pattern Late 2001 Rice
