用电量是评价用电的基本指标之一。获取及时准确的EPC时空动态数据对于理解和实际部署电力资源至关重要。在这项研究中，EPC模型开发使用稳定的夜间灯光时间序列数据从国防气象卫星计划业务线扫描系统（DMSP/OLS）。利用该模型对1995 - 2008年中国大陆县级生态环境保护的空间格局进行了重构。此外，还分析了EPC的时空动态，并得出以下结论。(1)EPC模型可靠地代表了EPC的时空动态在中国大陆约70%的准确性。(2)中国大陆大部分地区生态环境质量处于中低水平，时空差异明显，高水平生态环境质量中，58.26%集中在东部地区。京津唐、沪宁杭、珠江三角洲、山东半岛、辽中南、四川盆地等六大城市群面积占中国大陆总面积的10.69%，用电量占总用电量的39.23%。(3)1995 - 2008年中国大陆大部分地区的EPC都在增长，64%的大陆地区EPC增长显著。1995 - 2008年，61.62%的东部地区和80.65%的中部地区的EPC适度增加，而75.69%的西部地区的EPC没有显著增加。与此同时，沪宁杭地区、珠江三角洲和山东半岛分别有77.27%、89.35%和66.72%的地区EPC高速增长。京津唐地区和辽宁中南部的EPC分别有71.12%和72.13%出现了适度的增长，而四川盆地有56.34%没有出现显著的增长。
Electric power consumption (EPC) is one of the basic indices for evaluating electric power use. Obtaining timely and accurate data on the spatiotemporal dynamics of EPC is crucial for understanding and practical deployment of electric power resources. In this study, an EPC model was developed using stable nighttime lights time-series data from the Defense Meteorological Satellite Program Operational Linescan System (DMSP/OLS). The model was used to reconstruct the spatial patterns of EPC in Chinese Mainland at the county level from 1995 to 2008. In addition, the spatiotemporal dynamics of EPC were analyzed, and the following conclusions were drawn. (1) The EPC model reliably represented the spatiotemporal dynamics of EPC in Chinese Mainland with approximately 70% accuracy. (2) The EPC in most regions of Chinese Mainland was at low to moderate levels, with marked temporal and spatial variations; of high-level EPC, 58.26% was concentrated in eastern China. Six urban agglomerations (Beijing-Tianjin-Tangshan region, Shanghai-Nanjing-Hangzhou region, Pearl River Delta, Shandong Peninsula, middle-south of Liaoning Province, and Sichuan Basin) accounted for 10.69% of the total area of Chinese Mainland but consumed 39.23% of the electricity. (3) The EPC of most regions in Chinese Mainland increased from 1995 to 2008, and 64% of the mainland area showed a significant increase in EPC. Moderate increases in EPC were found in 61.62% of eastern China and 80.65% of central China from 1995 to 2008, whereas 75.69% of western China showed no significant increase in EPC. Meanwhile, 77.27%, 89.35%, and 66.72% of the Shanghai-Nanjing-Hangzhou region, Pearl River Delta, and Shandong Peninsula, respectively, showed high-speed increases in EPC. Moderate increases in EPC occurred in 71.12% and 72.13% of the Beijing-Tianjin-Tangshan region and middle-south of Liaoning Province, respectively, while no significant increase occurred in 56.34% of the Sichuan Basin.
