Evaluation System Research On Economic Utilization And Security Of Manganese Resources

Sustainable utilization of mineral resources and resource security is one of the common concern of human society. The rapid development of the economy in China promoted growing demand for mineral resources and utilization of manganese resources. Emergence of numerous mill run plants meet the manganese ore demand of Chinese industry to some extent. However, lacking of supervision and effective management, many manganese ore mill run plants focused on the immediate economy benefit instead of paying attention to scientific and technological innovation and environmental protection issues. Thus problems such as resources waste and serious environmental pollution arouse. Therefore, evaluation system research on development and utilization of manganese resources in China is in need for further societal and economic development.In the paper, the development history, realistic situation and existed problem etc. of sustainable utilization of mineral resources and resource security were dissertated. Also the technical methods in domestic and foreign for sustainable utilization of mineral resources and resource security were analyzed and summarized. Grey system theory and analytic hierarchy process were used to evaluate the sustainable utilization and resource security conditions of manganese resources in China. The key findings of the paper are following:l.The validity of the model is verified by the way of calculation and precision-test based on true data. Grey relational analysis of variety of factors which impact on China's steel output showed that:population growth and economic development are the two main factors impact on China's steel output, the per capita GDP and the construction industry output are great factors impact on China's steel output.Calculated by GM (1,1) gray prediction model, China's steel output in coming several years were predicted, then China's demand for manganese resources in coming several years were predicted based on relationship of consumption of manganese resources and steel output.2.The situation of sustainable utilization of mineral resources and resource security were evaluated by using analytic hierarchy process (AHP). Result showed, Capacity of the sustainable development remain in weak state; Safety and security capabilities remain in unsafe state. The situation is fairly severe.The analysts believe that the advantages of Chinese manganese industry is the huge market demand, while low level of manganese resources reserve and manganese resource utilization are pressing problem for Chinese manganese industry. The main problems of safety and security situation are sustainable development of industry, the environment problem, low capacity of sustainable usage. However, the high level of Import concentration, the reliability of transport channel, the high proportion of Import manganese ore, the availability of international market and some other issues are serious too.3. The study showed that the capacity for manganese sustainable utilization and resource security remained in fairly severe conditions in China. Finally, several important issues for Chinese manganese industry development were discussed and commented, they were sustainable utilization of resource,environmental pollution and environmental management,sustainable competitiveness of industry and utilization of resources overseas, and some suggestions were put forward.
