第一代小地老虎危害程度的模糊回归预测模型的研究

A Studies of Forecasting Model of Fuzzy Regression on The Damage Level of The First Generation of Agrotis Ypsilon (Rottemberg)

对第一代小地老虎危害程度的模糊回归预测模型进行了研究,建立了其预报体系（模糊隶属函数集）,对历史资料进行了回代验证,其符合率达91.3％,将1990年作为独立样本进行试报,预测结算与实测相符。

From studies for Fuzzy Regression Model, the authors deduced a system (Fuzzy set )to forecast the damage level of the first generation of Agrotis ypsilon (Rottemberg). The results tested the pest datas showed that the fitting rate was 91. 3%, and that the accuracy of forecast was right.
