摘要
为研究我国从2000年至今煤炭消费量的变化及其在地域上的分布特性,利用重心模型演算出2000—2012年我国煤炭消费重心的动态变化轨迹,进而分析2000年以来我国煤炭消费的空间格局。研究结果表示:2000年后我国煤炭消费量呈上升趋势,但煤炭消费量占能源总消费量的比率呈先上升再降低的趋势,转折点在2006年;2000—2012年我国煤炭消费重心移动总体呈现"W"状的趋势,先西南后西北再西南最后大幅折向西北,累计移动了135.78 km,平均速度为10.44 km/a;煤炭消费重心在经度上总体向西移动,在纬度上南北徘徊但最终向北移动。我国煤炭消费重心的演变轨迹一定程度上反映出了我国西部大开发的进程。
In order to study the coal consumption value variation from 2000 to the present date and the distribution features of the regions, a barycentre model was applied to calculate the dynamic variation track of China coal consumption barycentre from 2000---2012. Thus an analysis was conducted on the spatial pattern of China coal consumption since the year of 2000. The study results showed that after the year of 2000, China coal consumption value was in an uptrend, the coal consumption value in the national energy consumption ratio was firstly in an uptrend and then in a declined trend and the turning point was in the year of 2006. From 2000 to 2012, the baryeentre movement of China coal consumption was in a ＂W＂ trend generally. The barycentre was firstly in the south-west and then in the north-west and then in south-west finally was highly moved to south-west and the total movement was 135.78 km. The average speed of the movement was 10.44 krrdyear. The barycentre of the coal consumption generally was moved to the west in longitude and was wandered from south to north and from north to south, finally moved to the north. The barycentre evolution track of China coal consumption certainly reflect- ed the high development process of West China.
