A quantitative integrated evaluation of sustainable development of mineral resources of a mining city: a case study of Huangshi, Eastern China

摘要

It is generally considered that the non-renewable nature of mineral resources will make them gradually depleted over time. However, in the perspective of development availability of mineral resources in a long-term depends not only on their currently available amounts but also on future potential mineral resources (e.g. those undiscovered and low-grade ores) and substitutive renewable resources. In addition, it is influenced by factors like technology and capital. These factors interact with each other. As a result, it is possible to make the sustainable development of mineral resources by appropriate coordination between these factors. A new concept of Degree of Sustainable Development of Mineral Resources (DSDMR) and its conceptual model are proposed in this paper in the viewpoints of system science and sustainable development to evaluate the ability of sustainable development of mineral resources for a mining city. DSDMR refers to the ability of meeting needs of present and future generations for mineral resources by their logical distribution and substitution. An indicator system and a fuzzy integrated judgment model, which involve factors of resources, economy, society, environments and intelligence, are presented. They are used to evaluate DSDMR of Huangshi city, which is the most ancient and yet one of the most important mining cities producing iron and copper in China.
