Abstract: To predict demand for china iron and steel and iron ore resources is of great significance for industrial economy，environment and trade.Demand for crude steel was estimated according to the demand for construction，industrial areas and transportation industry.Output ratio of iron to steel and import interdependency for iron ore was analyzed.Demand for iron ore resources was measured.It can be concluded that total demand for steel will be over 800 million tons in 2013 and be close to 900 million tons in 2015 if ratio of steel exporting is 7%; If output ratio of iron to steel can be maintained in 0.95，it needs import 728 million tons iron ore in 2013 and over 800 million tons iron ore in 2015 when import interdependency is 58%.When import interdependency is 53%，it needs import 700 million tons iron ore in 2014 and about 740 million tons iron ore in 2015.Suggestions and measures about how to reduce output ratio of iron to steel and keep appropriate import interdependency were put forward.

Key words: Steel and iron, Iron ore, Resources, Prediction, Demand
