中国能源资源开发的时空格局与潜力评价(英文) 总被引:5,自引:2,他引:3
The issue of China's energy supply security is not only the key problem which affects China's rapid and sustainable development in the 21st century,but also the one which international attention focuses on.Based on the notable characteristic of spatial imbalance between energy production and consumption in China,this paper takes the evolution of China's primary energy resources development(excluding hydropower) from 1949 to 2007 as the study object,with the aim to sum up the evolutive characteristics and laws of China's energy resources development in the past nearly 60 years.Then,based on comprehensive considerations of coal's,oil's and natural gas's basic reserves,qualities,geological conditions,production status,and ecological service function of every province,this paper adopts development potential index(DP)to evaluate the development potential of every province's energy resources,and divide them into different ranks.Conclusions are drawn as follows:(1) Generally speaking,China's gross energy production was increasing in waves from 1949 to 2007.From the viewpoint of spatial patterns,China's energy resources development has shown a characteristic of "concentrating to the north and central areas,and evolving from linear-shaped to "T-shaped" pattern gradually since 1949.(2) The structure evolution of China's energy resources development in general has shown a trend of "coal proportion is dominant but decreasing,while oil and gas proportions are increasing" since 1949.(3) At the provincial scale,China's energy resources development potential could be divided into large,sub-large,general and small ranks,four in all.In the future,the spatial pattern of China's energy production will evolve from "T-shaped" to "∏-shaped pattern".These conclusions will help to clarify the temporal and spatial characteristics and laws of China's energy resources development,and will be beneficial for China to design scientific and rational energy development strategies and plans,coordinate spatial imbalance of energy production and consumption,ensure national energy supply,avoid energy resources waste and disorderly development,and promote regional sustainable development under the globalization background with changeful international energy market. 相似文献

结构与效率因素对内蒙古能源强度变动的影响 总被引:2,自引:0,他引:2
计量分析能源强度变动的影响因素可为未来寻找节能途径提供参考.采用能源强度变化的完全分解模型,以1985-2006年为样本期,对影响内蒙古能源强度变化的结构因素和效率因素进行了计算.结果表明:在整个样本期内,结构因素始终是促使内蒙古能源强度上升的因素;而效率因素的作用则呈现出阶段性特征,2000年以前,效率因素起到了很好的节能效果,而之后则对能源强度的上升却表现出正向作用.因此,未来一段时期内,调整产业和产品结构,是内蒙古节能降耗的最大潜力所在;效率节能虽已取得较好效果,但仍有潜力可挖. 相似文献
