| 摘 要： | 以村镇资源当地化和能源的清洁可再生化为前提,通过将村镇能源系统的成本分解为经济成本和环境成本2部分,建立了村镇能源系统低成本要素定量化评价模型,其中环境成本以生命周期评价清单输出为数据基础.以15年为周期,将我国严寒地区、寒冷地区3个典型村镇的12个能源系统方案作为算例进行综合成本比较,从量化分析结果看,以化石燃料(煤炭、液化石油气)为主的能源系统经济成本较高、环境成本较高;以秸秆、柴薪为主的能源系统经济成本较低、环境成本较高;以秸秆气、沼气为主的能源系统经济成本和环境成本都较低,且人均综合成本小于5 000元,是未来农村能源系统规划的优选方案. |

| Abstract: | Quantitative assessment model of low cost element is first established by dividing rural energy system cost into economic cost and environmental cost.And the latter is determined based on output data of life cycle inventory.With 15 years as a life cycle,12 energy system schemes of 3 typical villages from freezing zone,cold zone in China are compared synthetically as case studies.From the quantitative result,the fossil energy(coal,LPG) system schemes have higher economic and environmental cost; straw and fuel wood energy system schemes have lower economic cost but higher environmental cost; straw gas and methane energy system schemes have lower economic and environmental cost,and the integrated cost is below 5 000 yuan·capita-1,which are the optimum schemes for the future rural energ |
| Keywords: | life cycle assessment clean and renewable energy village and town low cost energy system |
