中文摘要：
能源保障时空协调所表现的是国家或地区能源供应保障系统的整体发育状态。论文在全球和国家两个层次上分析了矿物燃料的空间分布状态及时空协调过程。全球以及美国和中国的实践恰恰证明：由于全球矿物燃料资源存在着明显的空间收敛特征，当工业化和城镇化发展不断寻求更高质量能源的消费需求时，国家能源供应保障系统的发育空间便迅速从区域或国家转向全球。换言之，只有消费需求增长（时间过程）与供应范围有效扩展（空间过程）两者有机协调国家能源供应保障体系才能实现正常发育。
英文摘要：
This study shows that the national energy supply system could extend its spatial bordering as the increasing demands for the fuels, especially oil and gas, due to the uneven distribution of mineral resources of the whole world. According to the long-term practices of national industrialization in both the United States and China, the domestic resources dominated the energy supply in the early days, but the international resources come to play a more and more important role eventually as the national economy is mature. According to statistics, the ratio of net energy import in the United States was 0.3% in 1950 and quickly increased to 62.8% in 2005. That means when the structure of production and consumption diversified up to 0.1%, the international flow of fossil fuels for the United States had an increase of 0.9%. In the meantime, however, the change pattern of fossil fuels＇ flow in China between 1952 and 2005 witnessed that the country＇s energy supply, just about a half size of that in the United States, experienced a spatial expansion by 39% when its imported oil increased rapidly in the last 15 years. Such a change strongly implies only when the increase of energy consumption, labeled as the time course, is in harmony with the effective space expansion of supply, titled as the space course, can the national energy supply system develop eventually.
