基于能源平衡表的中国能流图

能流图作为国家或地区能源统计数据的整理和展示工具,目前已在国际上得到广泛应用,但在我国的应用尚少。本文参照当前国际上普遍采用的能流图结构,适当调整了中国能源平衡表中的分类,并以其为主要数据来源绘制了2003年和2004年的中国能流图。通过与能源平衡表的比较,归纳了能流图所具有的若干优势。结果表明,能流图不但能够直观、定量地展示能源供应、转换和使用数量的全貌,而且可以揭示各个环节的能源利用效率水平,还便于同其他国家能流图进行比较。

China''''s Energy Flow Chart Based on Energy Balance Sheet

Energy flow chart,which is taken as a tool for sorting out and displaying energy statistical data,has been very popular in U.S.,U.K.,Netherlands and some other countries.But in China,few people are working on this area.This paper takes the energy flow chart structure that has been widely used in oversea as a reference.In order to satisfy the data demand,the author also adjusted the classification in the China's energy balance sheet.And then,the author drafts China's energy flow chart of 2003 and 2004.Comparing with the energy balance sheet,it sums up several advantages of China's energy flow chart.China's energy flow chart is not only an object and quantitative tool for showing a whole picture of energy supply,transformation and end use data,but also can reveal their energy utilization efficiency and make it easy to compare with energy flow charts of other countries.
