摘要

依据2007年在互助县北山林区甘肃鼢鼠的危害现状调查,实施人工捕杀与化学防治相结合的方法进行防治,试验研究结果表明,通过防治可明显降低鼢鼠密度,提高幼林成活率,鼢鼠的平均密度由防治前的69只/hm2下降到27只/hm2,幼林保存率由防治前的65%提高到80%。%Through the harm status survey of Gansu zokor in beishan forest of Huzhu County in 2007, the methods combining manpower with chemical control were carried out, the results showed that： prevention could decreased the density of zokor obviously and improve the survival rate of young plantation. The average density of zokor decreased to 23 capitals per hectare from 52 capitals per hectare, retention rate of young forest increased to 80% from 65%.
