| 摘 要： | 本文通过对１９５２年至１９９８年的资料分析表现，东太平洋地区的海温变化对江苏省太湖地区小麦赤霉病发生程度有着显著的滞后影响，在ＥＮＳＯ事件开始或维持的下一年赤霉病明显偏重发生，在此基础上，运用人工神经网络方法，建立了太湖地区小麦赤霉病的海温长期混合预报模型。

| Abstract: | An analysis of related data from 1952 to 1998 in this paper shows that the abnormality of SST in the east Pacific near equator has remarkable stagnant influence on the occurrence of winter wheat gibberellin in .Taihu region of Jiangsu province. The gibberellin situation is obviously worse following the year when ENSO event occurs or sustains. Based upon the above analysis, a long-range forecasting model of the gibberellin in Taihu region has been set up in the form of neural network. |
