预测春季农田害鼠发生程度。方法：运用微机，对影响春季农田害鼠发生程度的前期因子进行回归分析。结果：找出与发生程度相关性高的3个因子，即3月份捕获率、3月份雌鼠捕获率和上年12月上旬至当年2月上旬最大一次降水，然后用BASIC语言编写Fuzzy聚类程序进行运算，从而组建预测模型进行预测。结论：1994年预测值与实测值相吻合。 Predict the occurrence of pest in farmland in spring. Methods: Using computer, regression analysis was performed on the early factors that affected the occurrence of pest in farmland in spring. Results: Three factors were found to be highly correlated with the degree of occurrence, that is, the catching rate in March, the catching rate in March and the maximum precipitation in the first ten days of last year from early February to early February of the same year, and then the fuzzy clustering Program to calculate, so as to form a prediction model to predict. Conclusion: The predicted value of 1994 is consistent with the measured value.
