针对国民经济发展对矿产资源开发需求的不断增加,分析了矿产资源的可耗竭性和稀缺性,以及矿产资源可持续利用的必要性。利用云理论在处理模糊性与随机性指标方面的优势,研究了将定性定量转换的云模型方法应用到矿产资源可持续发展评价,并结合实际数据进行分析。结果表明,该方法提供了更加准确、更加直观的矿产资源可持续发展评价手段。 In response to the increasing demand for the development of mineral resources in the national economy, the depletion and scarcity of mineral resources and the necessity of sustainable utilization of mineral resources are analyzed. By using the advantages of cloud theory in dealing with fuzziness and randomness indexes, the cloud model with qualitative and quantitative transformation is applied to evaluate the sustainable development of mineral resources, and the actual data are used to analyze it. The results show that this method provides a more accurate and intuitive evaluation method for the sustainable development of mineral resources.
