| Abstract: | Based on the data of SST and winter wheat scab in Taihu lake of Jiangsu Province from 1951 to 1998, the statistical analyses about the influence of abnormality of SST in pacific round equator on occurrence of winter wheat scab in Taihu lake area were carried out. It was found that situation of wheat scab would often be heavier in the next year when ENSO begin or last. Finally, a mixed long term prediction model of wheat scab was developed with the method of ANN (artificial neural network). |
