摘　　要：基于生命周期评价方法,建立了硬木直燃发电的清单数据,运用ILCD Midpoint+方法针对6种环境影响类型进行评价,并分析了造成各类环境影响的主要污染物,同时,在6种环境影响类型方面对多种发电方式进行了对比。结果表明:硬木直燃发电过程的环境影响主要来源于种植过程和发电过程,其中全球变暖主要来自发电过程,其余5种环境影响类型主要来自种植过程;氮氧化物、硫氧化物、氨、温室气体是造成各单元过程环境影响的主要因素;在环境影响方面,与水力、风力、光伏发电方式相比,硬木直燃发电具有一定劣势,但其产生的环境影响远低于传统化石能源发电方式。Based on the life cycle assessment method,inventory data of hardwood used in direct combustion power generation was established.The ILCD Midpoint+method was used to evaluate six environmental impact types,and the main pollutants causing various environmental impacts were analyzed.At the same time,multiple power generation methods were compared in terms of six environmental impact types.Results show that the environmental impact of the direct combustion of hardwood for power generation mainly comes from the planting process and power generation process,with global warming mainly coming from the power generation process,and the other five types of environmental impact mainly coming from the planting process.Nitrogen oxide,sulfur oxide,ammonia and greenhouse gas are the main factors causing environmental impact of each unit process.In terms of environmental impact,compared with hydro power,wind power,and photovoltaic power generation methods,hardwood direct combustion power generation has certain disadvantages,but its environmental impact is much lower than traditional fossil energy power generation methods.
