基于灰色关联支持向量机的中国粮食产量预测模型

研究我国粮食生产系统的变动规律,做好粮食产量科学预测不仅是制定农业政策的重要依据,而且对于保证我国的粮食安全具有重要意义。鉴于粮食生产系统的复杂性和信息不完全性,在对粮食生产系统灰色关联分析的基础上,确定出影响粮食产量的主要因子,然后根据支持向量机回归原理,建立了基于灰色关联支持向量机的预测模型。预测结果表明该模型具有较高的预测精度,为粮食产量预测提供了一条新的途径。

Application of the Grey Relational Analysis and Support Vector Machine for Forecast of China Grain Production

The forecast of grain production is not only an important resource for establishing agriculture policy but also is of great significance to ensure our nation's food security based on studying the change rule of our country grain production system.In view of the fact that the complexity and incomplete information of grain production system,the primary factors influencing the grain production is decided on the basis of the grey ralational analysis of the grain producing system,then,the grey ralational analysi...
