【摘要】：煤炭是我国铁路主要运输货种之一。根据我国铁路运煤基本特点,基于铁路运输网中的节点(编组站和煤炭下水港口),采用空间距离、时间距离和连接性等指标对煤炭铁路运输网络可达性空间格局进行了研究。结果表明:①空间距离可达性呈明显的中心—外围格局;时间距离可达性受线路技术等级、高等级客车开行等因素影响,尽管总体上也为中心—外围格局,但圈层结构明显向华东、华北地区偏移;连接性以阜阳北为中心,呈十字状伸展。②煤炭铁路运输网络连接性最为均衡,时间可达性、空间可达性次之,三者间差距并不明显。③煤炭下水港口空间可达性相近,但时间可达性和连接性有所差异,国铁煤运专线下水港口可达性优于国铁客货混跑线路,企业煤运专线港口可达性较差。
[Abstract]:Coal is the main transport of goods in China Railway. According to one of the basic characteristics of China's railway transportation, railway transportation network based on node (marshalling station and coal water port), the space distance, time distance and connectivity index of transportation network accessibility pattern of coal railway. The results showed that the spatial distance accessibility is obviously the core periphery pattern; time distance accessibility by technical level of high grade passenger train lines, impact and other factors, although the overall for the core periphery pattern, but the circle structure obviously to the East, north to Fuyang North migration; connectivity as the center, a cross shaped. The railway transportation of coal network connectivity is the most balanced, time accessibility, spatial accessibility of the gap between the three is not obvious. The coal water near port spatial accessibility, but time accessibility and connectivity The difference in iron, coal line water port accessibility is better than the national railway line for mixed passenger and freight traffic, port enterprises coal line poor accessibility.
