| 中文摘要: |
| 采用模糊多级判别预测小麦叶锈病发生趋势的方法，对曲阜市１９８３～１９９７年共１５ａ小麦穗期叶锈病发生趋势系统观测资料进行数量分析，建立起小麦叶锈病发生趋势预报模型，拟合率达８６７％，并用现有模型预测１９９８年病害发生等级，预测结果与实际情况相符。为该病害的预测预报提供了新的方法，对指导大田防治有实际意义。 |
| 英文摘要: |
| Based on the related data during the period of 1983-1997 in Qufu, Shandong Province, a fuzzy multistage distinction analysis model was set up for occurrence trends of wheat leaf rust. The fitting rate between predicted and observed data was 86.7%. This new method could also be used for forecasting of occurrence of wheat leaf rust. |
