【摘要】：以1991,2000,2010年中國主要城市煤炭鐵路交流數(shù)據(jù)為基礎(chǔ),分析了煤炭調(diào)出、調(diào)入以及空間交流格局的變遷。結(jié)果表明:中國煤炭調(diào)出城市逐步向南部和西部地區(qū)擴(kuò)展,"三西"(山西、陜西和內(nèi)蒙古)成為目前煤炭調(diào)出量最多的地區(qū),2010年中國煤炭調(diào)出高值區(qū)與國家大型煤炭基地的分布高度吻合;煤炭調(diào)入?yún)^(qū)在空間上逐漸向西南、西北和華南延伸,高值區(qū)仍主要位于北方沿海和東北地區(qū),以港口和工業(yè)城市為主,河北、廣西和江西是調(diào)入量增長最快的省份。2010年中國形成了東北、華北、華東以及西南四大煤炭交流系統(tǒng),山西的影響力開始下降,陜西和內(nèi)蒙古的影響力迅速增強(qiáng);煤炭運(yùn)輸集中在少數(shù)鐵路,并主要運(yùn)往北方沿海港口,形成了3條"鐵路—海運(yùn)"聯(lián)運(yùn)的煤炭運(yùn)輸通道。城市中心性的研究結(jié)果表明,山西的出度增長減緩,陜西和貴州出度迅速增長;入度較高的城市仍以港口、工業(yè)型城市和經(jīng)濟(jì)中心為主,其中工業(yè)型城市增多,空間上從沿海、東北地區(qū)擴(kuò)展到東南部和中南部。
[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.
