摘　　要：将支持向量机方法应用于宁夏及其邻近区域的地震综合预测研究中,通过建立基于多种地震前兆异常的地震综合预测模型,初步探讨了支持向量机方法在宁夏地震综合预测中的应用情况。研究结果表明利用支持向量机形成的地震综合预测模型对宁夏及周边地区可能发生的地震震级具有一定的预测能力。The support vector machine approach is applied to research the comprehensive earthquake prediction in Ningxia and its adjacent area.By establishing a comprehensive earthquake prediction model based on a variety of precursory anomalies,the application of support vector machine method to the comprehensive earthquake prediction is preliminarily discussed in Ningxia.The research results show that the comprehensive earthquake prediction model formed by support vector machine method had some predictive power on the magnitude range on the earthquake which might occur in Ningxia and its adjacent areas.
