| 中文摘要:我国是畜产品生产消费的大国。随着畜产品种类的日益丰富, 畜产品消费结构也悄然变化, 为了避免市场
供需失衡, 研究预测我国畜产品消费量对引导制定较为合理的生产计划有着十分重要的意义。基于此, 构建了基于
灰色关联分析和支持向量回归机的畜产品消费量组合预测模型。灰色关联分析为组合预测提供了选取单项预测模
型的依据, 确保了参与组合预测的单项预测模型的质量, 支持向量回归机以其良好的学习泛化能力用于组合预测中,
可以对复杂环境下的事物做出较为准确的预测。在上述理论与方法研究的基础上, 将基于灰色关联分析和支持向
量回归机的组合预测模型综合应用于我国猪肉消费量的预测实践中, 通过实验结果比较分析, 验证了研究成果的
有效性。 |

| Abstract:China is a big country in the production and consumption of livestock products. Because the variety of livestock products
is increasing, the consumption structure of livestock products has also been changed. In order to avoid imbalance between supply and
demand in the market, it is significant to study and predict the consumption of livestock products in China, which can help to guide the
formulation of more reasonable production plans. Thus, a combinational forecast model based on Grey Correlation Analysis and Support
Vector Regression is built. Grey Correlation Analysis provides the guides for selecting individual forecast model for combinational
forecast model to ensure the quality of forecast. The Support Vector Regression is used in combinational forecast because of its good
generalization ability, which can be used in complex environments. According to the above theoretical research, the combinational
forecast model based on Grey Correlation Analysis and Support Vector Regression is applied to the prediction of Chinese livestock
product consumption. The effectiveness of the research is verified by comparative analysis. |
