摘要
以唐山市铁矿石产量的实际数据为基础,建立了唐山市铁矿资源的GM(1,1)预测模型,并且进行了后差检验,结果表明该模型是可靠的。利用该模型对唐山市未来5a铁矿资源供应量进行预测,从而指导该地区未来铁矿资源的合理供应,保障唐山市钢铁工业健康、持续发展。
Based on actual data of iron ore output of Tangshan, GM （ 1,1 ） prediction model for iron ore resource of Tangshan has been established and differences are examined. The results show that the model is reliable and can be used to predict iron ores resources supply in Tangshan in the coming 5 years, so that it can guide rational supply of the iron ore resource of this district in future and ensure healthy and continuous development of the iron and steel industry of Tangshan.
