文章基于长江经济带非金属矿产数据,利用地理信息系统(geographic information system,GIS)空间分析方法和脱钩模型研究2007-2018年期间该地区非金属矿采矿权分布的时空变化特征.结果表明:非金属矿开采重心呈现出向西部地区移动的趋势;非金属矿采矿权分布呈现"西南—东北"的空间格局,且非金属矿高开采强度区呈现出收缩趋势;非金属矿采矿权分布具有显著的空间正相关特性,其中,高-高类型区域分布在贵州、江西等省份,低-低类型区域分布在浙江、江苏、安徽等省份;非金属矿采矿权面积与经济增长脱钩状态稳定,脱钩情况理想,经济发展对非金属矿产开发依赖性减小;建筑石料用灰岩采矿权分布的时空规律和非金属矿采矿权分布的时空规律相似,均呈现开采重心向西部偏移的态势.该研究结果反映了在2007-2018年中国经济高速发展期间,长江经济带非金属矿采矿权分布的时空特征变化及其影响因素,为今后非金属矿产资源开发空间布局优化提供空间决策参考.
Analysis of temporal and spatial variation characteristics of non-metallic mineral mining rights in the Yangtze River Economic Belt,China
Based on the data of non-metallic minerals in the Yangtze River Economic Belt,this paper u-ses geographic information system(GIS)spatial analysis methods and decoupling models to study the temporal and spatial variation characteristics of the distribution of non-metallic mineral mining rights in the region from 2007 to 2018.The results show that the mining core of non-metallic mines is mov-ing to the western region.The distribution of non-metallic mineral mining rights shows a spatial pat-tern of southwest-northeast,and the high-intensity mining areas of the non-metallic mines show a shrinking trend.The distribution of non-metallic mineral mining rights has a significant positive spa-tial correlation.Among them,the high-high type areas are distributed in provinces such as Guizhou and Jiangxi,and the low-low type areas are distributed in provinces such as Zhejiang,Jiangsu,and Anhui.The area of non-metallic mineral mining rights is stably and ideally decoupled from economic growth,and economic development is less dependent on the development of non-metallic minerals.The temporal and spatial law of the distribution of mining rights for limestone for building stones is similar to that of the distribution of non-metallic mineral mining rights,and both show a shift of the mining core to the west.These results reflect the variations in the temporal and spatial characteristics of the distribution of non-metallic mineral mining rights in the Yangtze River Economic Belt and its in-fluencing factors during the period of rapid economic development of China from 2007 to 2018,thereby providing a reference for spatial decision-making in the future optimization of the development of non-metallic mineral resources.
