| 摘 要： | 选取旱、涝、震灾害之间的一步转移概率作为Ｂ－Ｐ人工神经网络训练样本的输入信息，建立了四川旱、涝、震的人工神经网络灾型预测模型。Ｂ－Ｐ网络模型应用于实例预测结果与用主分量分析法的趋势预测结果精度接近。

| Abstract: | A prediction model of drought,flood and earthquake disasters in Sichuan based on the artificial neural networks is developed and one step transitional probabilities among drought,flood and earthquake are selected as the input information of B P artificial neural network.The examples show that the prediction results of drought,flood and earthquake trend by this method approximate to that by the principal component analysis. |
