摘要:

矿业在国民经济发展中起着重要的作用,分析湖北省东部矿产资源违规开采点的空间分布特征,探讨成因机制,对遏制违法开采行为、有效保护和合理利用矿产资源具有重要意义。利用遥感影像解译结合野外调查获取的2011-2014年矿产资源违规开采点数据,采用空间插值、核密度分析、缓冲区分析和重心模型等方法,从全部矿产资源、主要违规矿种的违规开采点密度分布特征和违规开采点重心转移两个层次、三个方面揭示矿产违规开采点空间转移特征。结果表明:研究期内违规开采点集中分布在大冶市和阳新县,具有向大冶市与铁山区结合部转移的特点,但金属矿产违规重心几乎不变,建筑石料用灰岩逐年向阳新县转移,主要受矿产资源禀赋特征、交通便捷程度、不同行政单元结合部和经济发展刚性需求等因素的影响;违规开采点重心呈“Z”型转移,迁移轨迹与监管疏漏导致的不同区域违规开采数量变化和重要矿种分布情况有关。

Abstract:

As the mining industry plays a vital role in the development of the national economy in China,it is of great importance to analyze spatial distribution characteristics of illegal mining sites of mineral resources and formation mechanisms in eastern Hubei to restrain illegal activities and realize effective protection and rational utilization. By using map delineation data spanning 2011 to 2014 on illegal mining sites obtained via integration of remote sensing image interpretation,field investigation and adopting methods like spatial interpolation,kernel density analysis,buffer area analysis and gravity center model,spatial transfer characteristics of illegal mining sites are revealed from two levels and three aspects,namely the density distribution of illegal mining sites of all mineral resources,main illegal minerals and the gravity movement of illegal mining sites. It was found that in the study area,illegal mining sites have been concentrated in Daye city and Yangxin county,following a trend of shifting to the fringe of Daye city and Tieshan district. But the illegal focus of metal minerals remains almost constant and limestone for building is being transferred to Yangxin county year by year. These patterns are influenced mainly by the inherent characteristics of mineral resources,traffic conditions,the fringe of different administrative units and rigid demands of economic development. The gravity centers of illegal mining sites present Z type transfer and the gravity movement is related to changes of illegal mining quantity in different regions and the distribution of important minerals caused by regulatory oversight.
