摘要
建立了小麦穗期鼠害动态的经济阈值模型，同时根据小麦的不同产量水平和不同的经济系数，提出了相应的鼠害的经济允许受害水平和经济阈值．
By investigating,the mordel of dynamic economic thershold for the rodent damage was set up .during wheat ear periods in this paper,and the economic injury level and economic thershold were provided under the different yield level and economic coefficients during wheat ear periods.
