中文摘要：

节能减排是涉及多因素的系统工程，目前常用的考核方法多是对单位GDP能耗和主要污染物排放总量分别考核。针对目前中国节能减排的现状，提出把节能和减排两大任务并入一个系统内进行效用分析和评价。构建包含COD，SO2，单位GDP能耗三个子系统的节能减排系统。并给出了节能减排系统的综合效用模型，提出了一种针对节能减排整个系统的综合评价考核办法。

英文摘要：

Energy-saving ＆ pollutant emission reduction is a systematic project involving multiple factors. The general methods are to assess unit GDP energy consumption and emissions of major pollutants respectively. According to the status quo of energy-saving ＆ pollutant emission reduction, the paper proposes to merge energy-saving target and emission reduction target into the one system and to analyze the system. The system includes three sub- systems, COD system, SO2 system, unit GDP energy consumption system. The paper proposes a utility analysis model and a comprehensive evaluation assessment method for the energy-saving ＆ pollutant emission reduction system.
