稻瘿蚊发生趋势的B—P网络预测模型

A Forecast Model for Come into Existence of Orsedia Oryzae Based on B - P Network

根据历年的积累资料，采用Ｂ—Ｐ人工神经网络系统，对广西邕宁县晚稻稻瘿蚊发生进行了预测研究。结果表明：该方法性能良好，预测准确，可望成为植物病虫害预测预报的一种新的有效辅助手段。

Using the historal data, we have put forword a B -- P network forecast model. We also using this model to forecast the emerge and degree of orsedia oryzae of late rice production in Fu Ning area of Guang Xi province. The result indicated that this method have good performance, and have a exact forecasting effect. This method have the hope to turn into a effective means for the prediction of plant diseases and insect Pests.
