摘　　要：采用简化的生命周期评价(LCA)方法,将水库生命周期划分为建材生产、材料运输、建筑施工、水库蓄水淹没初期和稳定运行期等阶段,构建了适合于各类型水库温室气体(GHG)排放计算的方法;以低丘区浅水型防洪为主的峡江水库为例,计算分析了该水库生命周期GHG排放量和阶段分布特征,并计算对比了水库发电GHG排放系数。结果表明,该水库生命周期GHG排放主要发生在运行期,且绝大部分由水库淹没水体产生;水库发电GHG排放系数比以发电为主的水电站要高,但仍然远低于化石燃料发电。Based on simplified Life Cycle Assessment （LCA） method, the life cycle of reservoir is divided into different phases of building materials production, materials transportation, construction, early impoundment and routine operation, and a method that is suitable for various types of reservoirs is set up for calculating Greenhouse Gas （GHG） emission. Taking Xiajinag Reservoir as an example, which is a typical hilly reservoir and takes flood control as its most important task, the life cycle GHG emission of Reservoir is studied, the emission characteristics for different phases are analyzed, and the reservoir generation GHG emission factor is also compared. The results show that most of GHG emission of Reservoir is mainly formed in the operation period and largely due to the reservoir submergence. Although the GHG emission factor of Reservoir is higher than those of the reservoirs with electricity generation as their main task, but it is still much lower than fossil fuel power generation.
