摘要
在介绍世界铁矿资源概况以及我国铁矿资源供需现状的基础上,对影响我国铁矿资源需求的主要因素进行了深入分析,然后利用BP神经网络建立了铁矿资源需求情景分析模型,并利用2001—2011年相关数据进行了测算,得出2013—2025年我国铁矿资源需求情景。研究结果表明:未来我国铁矿资源进口依存度将达到25%～35%,虽然有所降低,但仍然比较高。
The main factors influencing the iron ore demand are deeply analyzed on the basis of the introduction of the general situation of iron ore in the world and its present situation of supply and demand in China. Then, demand scenario model with BP software is established with the use of BP ANN,and makes a prediction based on the related data from2001 to 2011 to obtain the future demand scenarios of iron ore minerals in China from 2013 to 2015. The results show that the import dependence of iron ore minerals in China will arrive 25% -35%, already declines but still remains relatively high.
