摘要: 针对环境资源、农业科技、社会投入等要素对粮食生产构成的多变量复杂系统预测问题,构建分数阶GM(1,N)预测模型。选取2010—2019年河南省粮食产量及相关因素数据,采用灰色关联分析方法筛选出对河南省粮食产量影响较大的三个因素建立FGM(1,4)模型,对河南省的粮食产量数据进行模拟、预测。建立FGM(1,1)模型、传统GM(1,4)模型与FGM(1,4)模型作对比,建模结果表明FGM(1,4)模型模拟误差为1.23%,模拟精度高,预测性能稳定。最后利用FGM(1,4)模型预测河南省2020—2025年的粮食产量,期望能为未来粮食产量预测和农业发展规划提供依据。

Abstract: A multivariable fractionalorder GM(1,N) model was established to predict grain yield in order to solve the problem of multivariable complex system prediction of grain production caused by environmental resources, agricultural science and technology, and social input. Based on the data of grain yield and related factors in Henan Province from 2010 to 2019, three factors that have a great impact on Grain Yield in Henan Province are selected by grey correlation analysis method, and an FGM(1,4) model is established to simulate and predict the grain yield data in Henan Province. The FGM(1,4) model and traditional GM(1,4) model are established to compare the validity of the model, the modeling results show that the FGM(1,4) model has a high degree of curve fitting and good prediction performance,whose simulation error is 1.23%.Finally, the FGM(1,4) model is used to predict the grain output of Henan Province from 2020 to 2025. It is expected to provide a basis for the forecast of grain yield and agricultural development planning in the future.

Key words: grain security, grey correlation analysis, fractionalorder GM(1,N) model, grain yield forecast
