高原鼢鼠是天祝县高寒草甸草地的优势鼠类,危害严重。5月鼠密度在5.2只/hm2～15.9只/hm2之间,至9月造成牧草损失322kg/hm2。通过调查鼠密度和牧草损失量,结果充分显示鼢鼠的种群密度与其造成的损失量之间呈明显的正相关关系,其回归方程式为：M=5.07X＋26.06。通过防治综合分析研究后提出在甘肃天祝县高寒草甸草地高原鼢鼠的防治指标为8.3只/hm2,在5月份防治。

Plateau zokor of alpine meadow in Tian-zhu County, as a kind of dominat species, causes serous damages. In May, the density of zokor is between 5.2 per hectare and 15.9 per hectare, forage loss until September is 322 kg/hm2. The in- vestigation on zoker density and forage loss demonstrated positive correlation between them, the regression equation is M= 5.07X+26.06. By integrated analysis and study, this paper points out that the control index of plateau zokor is 8.3 per hectare of alpine meadow in Tian-zhu County of Gansu Province, and May is proved to be the suitable time for control.
