Abstract

Abstract

Based on the four dimensions of resource, industry, environment and market, this paper established the comprehensive evaluation index system of iron ore in China, and integrated the entropy weight method and technique for order preference by similarity to an ideal solution (TOPSIS)method to quantitatively evaluate the safety situation of iron ore in China from 2000 to 2015. Resource security index and market safety index showed downward trends as a whole during the studied period. The impact of industrial safety index on the safety of iron ore was initially small and then increased rapidly. The environmental safety index declined rapidly before the year 2005 and was followed by a positive impact on the safety of iron ore. The comprehensive security situation of iron ore showed a downward trend in 2000-2009 while increased slightly in the volatility in 2009-2015, but still in a critical state of insecurity. To guarantee the safety situation of iron ore in China, the domestic iron ore supply must be improved by intensifying geological exploration and saving resources, and the international cooperation and global resources layout should also be intensified.
