摘 要: 我国煤炭资源的生产和消费在空间上的错位分布,导致了省际煤炭资源的大规模流动。为揭示全国煤炭交流网络的整体结构演变以及煤炭规划区的发展,本文运用社会网络分析方法(social network analysis,SNA)对2001-2007年我国铁路行政区域间煤炭交流数据进行分析,并借助SNA的图论分析视角,得到:自2001年来,我国煤炭交流整体网的密度呈现明显的增大,交流空间出现分化等结论。 Due to the dislocation of coal production and consumption,coal flow among provinces has become a large-scale spatial phenomenon in China.In order to reveal the evolution of coal flow network and the development of plan districts of coal resources,this paper analyzed the statistical data of rail-transported coal exchange among provinces from 2001 to 2007.With the help of social network analysis,this study has come to some conclusions like the network density of coal exchange in China showing significant increases and the exchange space of coal resources dividing since 2001.
