工业是能源消费的主要源头,城市是能源消费的主要场所,划分城市工业行业能源消费强势等级,有利于锁定城市能源消费重点行业,为中国城市化、工业化进程中的产业能源管理提供必要信息.在回顾工业能源消费基本关系基础上,确定了工业行业能源消费贡献率、经济贡献率和能源效率作为能源消费基本参数.以中国总体水平作为比较基准,界定了能源消费距离指数基本概念.按照距离指数数值的大小将工业行业能源消费等级划分为从巨大强势到巨大弱势之间的9个不同等级,指出了应关注的工业行业能源消费等级类型.以重庆为例,演示了工业行业能源消费强势等级划分方法的应用,确定了重庆主要工业行业在能源消费方面强势等级,找出了能源管理中值得特别关注的工业行业.
Energy is mainly consumed by the urban industry system,thus grading industrial sectors for their energy consumption may help to identify the concerned industrial sectors and provide necessary information for industrial energy management in China's industrialization and urbanization.In present article,based on a review of the fundamental relationships between energy consumption and industrial sectors,the contribution rates and energy efficiency of industrial sectors are chosen as typical parameters for energy consumption.The concept of distance index of industrial sectors for energy consumption is defined through China's average level as a reference base.The grade of industrial sectors in energy consumption is classed into 9 types from extreme advantage to extreme disadvantage according to the scope of distance index values,and the types of industrial sectors that need to be more concerned are pointed out.Taking Chongqing as a case study,the application for grading industrial sectors for their energy consumption was exhibited,by which,the main industrial sectors are grated and the industrial sectors that should be special concerned in energy management are determined.
