绿色矿山是推动矿业绿色转型的重要平台和抓手,开展相关研究对推动矿业高质量发展和建设美丽中国具有重要现实意义.该研究基于1101个国家级绿色矿山样本数据,采用非均衡指数、标准差椭圆法、Moran's I、热点分析、核密度估计和地理探测器等方法,在分析地级单元尺度上绿色矿山的空间分布特征的基础上,从资源、环境和社会三个维度选取影响因子,探究其对绿色矿山密度空间分异的驱动作用.结果表明:(1)中国绿色矿山空间分布呈现出"东南密集,西北稀疏"的空间分异特征,与胡焕庸线所形成的地理格局具有空间一致性.(2)绿色矿山空间集聚特征显著,表现出明显的空间溢出效应,热点区域凸显了明显的极化现象,在空间上呈现出包含3个较大的核心区和5个较小的核心区的多核式"核心-边缘"的分布特征.(3)单因子对绿色矿山的空间分异影响显著,但解释度不高,双因子交互解释力显著增强,这种增强的关联主导因子为生态敏感度、路网密度与矿产地密度.该研究可为进一步发挥地理主导因子优势,形成各具特色的绿色矿山发展模式提供依据.
Spatial Distribution Characteristics and Influencing Factors of Green Mines in China
Green mining serves as an important platform and catalyst for promoting the green transformation of the mining industry. It is of great practical significance to conduct relevant research to promote the high-quality development of mining industry and build a beautiful China. Based on 1101 national-level green mine sample data,this work utilized uneven index,standard deviation ellipse method,Moran's I,hotspot analysis,and kernel density estimation to analyze the spatial distribution characteristics of green mines at a prefecture-level scale. Additionally,the study employed geographical detectors to calculate the explanatory power of influencing factors on the spatial differentiation of green mine density distribution. Results show that:(1) The spatial distribution of green mines in China exhibits a distinct spatial differentiation pattern,with a concentration of mines in the southeast and a relative scarcity in the northwest. This spatial distribution is consistent with the geographical pattern formed by the Hu Huanyong Line. (2) The spatial agglomeration of green mines is notable,exhibiting a discernible spatial spillover effect. The hotspot area exemplifies a pronounced polarisation phenomenon,manifesting as a multinuclear 'core-edge' distribution,comprising three larger core areas and five smaller core areas. (3) The influence of a single factor on the spatial differentiation of green mines is significant,but the degree of explanation is not high. The explanatory power of two-factor interaction is significantly enhanced,and the dominant factors associated with this enhancement are ecological sensitivity,density of road network and the density of mining sites. This study provides a basis for further exerting the advantages of geographic dominant factors and forming the development mode of green mines with different characteristics.
