【摘要】：中国能源产消不平衡导致在空间上形成大规模的能源流动,流动格局不断发生变化,需要采用纵横向耦合视角分析区域能源流动的演进过程及特点。文章构建衡量区域能源流向和流速的指标,通过多次分层聚类将1995年~2012年30个省(市、区)在煤炭、石油和天然气供需方面的职能类型划分为7种,重点分析汇流地、输流地和中转地,各能源流动主要特点为:第一,煤炭在省与省之间调运频繁而中转规模适中,表现为沿海汇流、稳定输流、内陆中转;第二,石油流动大进大出,表现为分散汇流、集中输流、中转枢纽;第三,天然气以本地供应为主,表现为经济圈汇流、多源供应、小进小出。总体来看,中国能源消费的分布轴线逐渐靠近胡焕庸线,与人口分布的趋势基本一致。
[Abstract]:The imbalance of energy production and consumption in China leads to the formation of large-scale energy flows in space, and the flow pattern is constantly changing. It is necessary to analyze the evolution process and characteristics of regional energy flows from the perspective of vertical and horizontal coupling. In this paper, the index of regional energy flow and flow velocity is constructed, and the functional types of 30 provinces (municipalities, districts) in coal, oil and natural gas supply and demand from 1995 to 2012 are divided into 7 types by multiple stratified clustering, with emphasis on the analysis of confluence areas. The main characteristics of each energy flow are as follows: first, coal is frequently transferred between provinces and provinces, and the transfer scale is moderate, which is manifested as coastal confluence, steady flow, inland transit; second, large oil flows in and out. Third, the natural gas supply is mainly local supply, the performance is economic circle confluence, multi-source supply, small input and small output. In general, the distribution axis of China's energy consumption is gradually close to Hu Huanyong line, which is basically consistent with the trend of population distribution.
