【摘要】：以1991,2000,2010年中国主要城市煤炭铁路交流数据为基础,分析了煤炭调出、调入以及空间交流格局的变迁。结果表明:中国煤炭调出城市逐步向南部和西部地区扩展,"三西"(山西、陕西和内蒙古)成为目前煤炭调出量最多的地区,2010年中国煤炭调出高值区与国家大型煤炭基地的分布高度吻合;煤炭调入区在空间上逐渐向西南、西北和华南延伸,高值区仍主要位于北方沿海和东北地区,以港口和工业城市为主,河北、广西和江西是调入量增长最快的省份。2010年中国形成了东北、华北、华东以及西南四大煤炭交流系统,山西的影响力开始下降,陕西和内蒙古的影响力迅速增强;煤炭运输集中在少数铁路,并主要运往北方沿海港口,形成了3条"铁路—海运"联运的煤炭运输通道。城市中心性的研究结果表明,山西的出度增长减缓,陕西和贵州出度迅速增长;入度较高的城市仍以港口、工业型城市和经济中心为主,其中工业型城市增多,空间上从沿海、东北地区扩展到东南部和中南部。
[Abstract]:Based on the data of coal railway exchange in major cities of China in 19912000 and 2010, this paper analyzes the changes of the pattern of coal transfer out, transfer and spatial exchange. The results show that China's coal transfer cities gradually expand to the south and west, "three west" (Shanxi, Shaanxi and Inner Mongolia) have become the regions with the largest amount of coal discharged at present. In 2010, the high-value areas of China's coal transfer are highly consistent with the distribution of the state's large coal bases; the coal transfer areas gradually extend spatially to the southwest, northwest and southern China. The high-value areas are still mainly located in the northern coastal and northeast regions, mainly in ports and industrial cities, and Hebei, Guangxi and Jiangxi are the provinces with the fastest growth in terms of incoming volume. In 2010, China formed four major coal exchange systems in Northeast, East and Southwest China. The influence of Shanxi began to decline, and that of Shaanxi and Inner Mongolia increased rapidly. Coal transportation was concentrated on a few railways and transported mainly to the ports along the northern coast, forming three "railway-seaborne" coal transport channels. The results of the city-centered study show that the growth of Shanxi's export rate is slowing down, and that of Shaanxi and Guizhou is growing rapidly, and the cities with higher entry are still dominated by ports, industrial cities and economic centers, in which the number of industrial cities has increased, and the space has been increased from the coastal areas. The northeast extends to the southeast and south-central regions.
