摘要
运用全局自相关、冷热点区分析、社会网络分析等方法，对2005-2014年中国煤炭资源流网络空间结构进行分析，得到结论：①我国煤炭资源流的源汇地的集聚性相对比较明显。②源汇地热、冷点区均呈现出明显的热点区-次热区-次冷区-冷点区的梯度空间分布格局。③煤炭资源流网络密度较低；山西、河北在网络结构中占据核心地位：山西、河北、内蒙古为节点流强度最高地区；山西-河北煤炭流为主要轴线。④煤炭资源流系统出现内部凝聚特征，各子群并未局限于某一地理区域；子群内外联系相对较弱，未实现一体化，整体上没有形成稳定的、联系紧密的网络结构。
Energy resources flow has been attracted more and more attention. Coal was the dominant energy in China, and it would also occupy the dominant role in the following decades. In this paper, we applied the Global Autocorrelation Analysis, Hot Spot Analysis, and Social Network Analysis to analyze the characteristics of cyberspace construction of coal resources flow. Some conclusions were drawn. （1） Spatial aggregating characteristics of source and terminal regions were prominent. （2） Hot-cold spot regions presented the significant pattern of gradient distribution, respectively. （3） Network density of coal resources flow was small; Shanxi and Hebei were the core nodes in the network of coal resources flow; Shanxi, Hebei, and Inner Mongolia were the regions that node intensity of coal resources flow was the largest; Coal resources flow from Shanxi to Hebei was the main axis of the network. （4） Coal resources flow system showed the characteristics of internal condensation, and each subgroup was not limited to a geographical area; the contacts within each subgroup and among subgroups were still relatively weak, and it was not formed a stable and interconnected network structure.
