【摘要】 矿产资源自然区划是矿产资源区划体系的基础层级,是矿业生产力布局和矿产资源规划管理调控的基础依据。本文首先界定了矿产资源自然区划的内涵、特征、目标和原则,构建了基于空间叠置法、GIS核密度分析和专家研判法的自然区划技术流程,并开展了全国矿产资源自然区划实证研究。以自然地质构造单元和栅格单元为基本分析单元,重点考虑矿产资源分布的集中性和区域成矿作用的统一性,将全国划分为28个资源富集区,勾勒了全国矿产资源空间分布轮廓和格局,以期探寻规律认知并为完善矿产资源区划体系、提升矿产资源区域差别化管治能力提供科学依据。更多还原

【Abstract】 The natural zoning of mineral resources is the basic level of mineral resources zoning system,which is also the basis of the mining productivity layout and the mineral resources planning and management.This paper firstly defines the connotation,characteristics,objectives and principles of mineral resources natural zoning,constructs the zoning technical process based on spatial overlay,GIS kernel density estimation and expert judgment method,and carries out the empirical study on the natural zoning of mineral resources in China.Taking the natural geologic tectonic unit and the grid unit as the basic analysis unit,focusing on the concentricity of mineral resources distribution and the uniformity of regional mineralization,the country is divided into 28 resource-rich areas,with a view to explore the law cognition and provide the scientific basis for perfecting the mineral resources zoning system and improving the regional governance of mineral resources.更多还原
