摘　　要：建立了基于环境影响和资源消耗的苹果树修剪枝条直燃发电系统生命周期综合评价模型并进行了分析。结果表明,苹果树修剪枝条直燃发电综合性能指标0.055~0.225 (人·年)/(万kW·h),其环境影响对综合性能的作用远大于资源消耗,并且呈现局地性>同等性>区域性>全球性的特征。苹果树修剪枝条直燃发电综合评价最大值仅为燃煤发电最小值的57.25%,表现出较好的优越性。苹果树修剪枝条直燃发电的综合性能对固体废弃物总量和原料消耗率最为敏感,因此对固体废弃物的有效管理和处置,以及对生物质锅炉和燃料品质的改进,能进一步提升苹果树修剪枝条直燃发电的环境效益。该研究为基于果树修剪枝条的直燃发电系统研究提供理论依据和参考数据。Based on environmental impact and resource consumption,a comprehensive evaluation model for life cycle of direct combus-tion power generation system of pruned apple tree branches was established and analyzed.Results showed that comprehensive perform-ance index of direct combustion power generation of pruned apple tree branches ranged from 0.055 to 0.225(person·year)/(10000 kW·h),and effect of environmental impact on comprehensive performance was much greater than that of resource consumption,and characteristics were local>equal>regional>global.The maximum value of direct combustion power generation of pruned apple tree branches was only 57.25%of the minimum value of coal-fired power generation,showing a good advantage.Comprehensive per-formance of direct combustion power generation of pruned apple tree branches was most sensitive to total amount of solid waste and raw material consumption rate.Therefore,effective management and disposal of solid waste,as well as improvement of quality of biomass boilers and fuels,can further improve environmental benefits of direct combustion power generation of pruned apple tree branches.Res-ults of this study could provide theoretical basis and reference data for research of direct combustion power generation system based on pruned fruit tree branches.
