模拟人工神经网络对小麦吸浆虫发生程度的预测
A neural network approach to occurrence degree forecasting for wheat midge
【摘要】 根据神经网络建模的基本原理,对陕西省关中地区小麦吸浆虫的发生程度资料进行处理分析,建立了神经网络发生适合度预测模型。结果表明:该方法的预测精度达到100%,为害虫的长期发生预测提供了一种新的方法。
【Abstract】 In this paper,occurrence degree neural network forecasting model was established by using occurrence degree data of wheat midge of Guanzhong area based on ANN basic principle.The forecasting results show:its prediction accuracy was 80%,and it offers a new method to predict plague of pest.
