黄土高原地区人口和粮食产量预测模型

THE PREDICTION MODELS OF POPULATION AND GRAIN OUTPUT IN THE LOESS PLATEAU REGION

本文应用不等间隔时间序列GM(1,1)模型对黄土高原地区的人口和粮食产量进行了预测分析,模型精度分别为95.68％和99.43％,从而为制订黄土高原地区综合治理开发方案提供决策依据。

In this paper, the population and grain output of the Loess Plateau region are predicted with the unequal interval time-series models. The accuracy of the models are 95.68% and 99.43% respectively. This provides a decision-making basis for working out a comprenensive exploitation plan in the region.
