| 摘 要： | 以太阳黑子和自相关因子为预测因子，采用逐步回归分析方法，建立了赣北棉铃虫发生趋势的超长期预测模型。该模型１９６６～１９９１年的历史符合率达８０．７７％，１９９２～１９９６年的预报确率达８０％。所建模型可以提前２ａ发出预报，据此对１９９７和１９９８年赣北棉铃虫的发生趋势进行了预测。

| Abstract: | The ultralong term prediction model of the occurrence trend of Helicoverpa armigera in Northern Jiangxi was established by stepwise regression analysis with the sunspot and autocorrelated factors as forecast factors. The historical coincident rate of the model reached 80 77% during 1966-1991, and its forecasting accuracy reached 80% during 1992-1996, respectively. It could be send out the forecast informations two years ahead based on the model. The occurrence trend of H. armigera were predicted in Northern Jiangxi in 1997 and 1998. |
