摘　　要：从生命周期的角度分析,各类新能源发电技术的开发、建设、运行过程,也会带来一定的温室气体排放,这引发了人们对于新能源发电技术"低碳"属性的担忧。遵循生命周期评价方法,在对国内外大量资料文献进行收集整理的基础上,对中国传统火电和主要新能源发电技术的温室气体排放系数进行了对比分析;并根据国家发展规划目标,对新能源发电替代火电的温室气体减排潜力进行了估算。分析结果表明,即使考虑生命周期内的排放,新能源发电技术的温室气体排放系数仍远远低于火电,新能源发电技术替代火电的温室气体减排潜力巨大。From the perspective of life cycle assessment（LCA）,the development,construction,operation of all kinds of new energy power generation technology do bring some greenhouse gas（GHG） emissions.This sparks ＂low carbon＂ property concerns of new energy power generation technology.Based on domestic and foreign relevant literature,this paper compares and estimates the GHG emission coefficients of traditional power generation and new energy power generation in China with the LCA,and then calculates the GHG mitigation potential of new energy power generation alternative to traditional coal-fired power generation,according to the national development planning objectives of new alternative energy generating.The results show that the GHG emission coefficients of new energy power generations are much lower than that of traditional coal-fired power generation even with LCA accounting,and the GHG mitigation potential of new energy substitution is still large.
