摘　　要：定量地分析了广梅汕铁路电气化改造工程的生态效应，主要探讨了改造过程中生物量损失、水土流失的生态负效应及改造后水环境、大气环境得到改善的生态正效应。结果表明，广梅汕铁路电气化改造施工造成的植被生物量损失共计334．5t，工程造成新增水土流失量为689．0t。电气化改造后，龙川机务段每年生产污水的污染物排放数量将会减少，其中油类将减少21．9kg，COD减少76．1kg，SS减少145．3kg。经过电气化改造，全线每年减少耗油2．16万t，每年向大气减少排放153．21tCO、1085．42tNOx、47．47tSO2、328t碳烟和110．06tCnHm。随着植被恢复措施功能的显现，其生态负效应是逐年减弱的，因而该线路电气化改造工程的生态正效应远远大于其负效应，改造工程会带来良好的生态效应。In this paper, the ecological effects of Guangzhou-Meizhou-Shantou railway electrification project, including negative effects and positive effects （e.g. improving water and atmosphere quality） were quantitively analyzed. The results showed that during the reconstruction period： 1） the vegetation biomass lost 334.5 t; 2） the reconstruction project incurred 689.0 t soil and water loss. After the electrification project was finished, the amount of water contaminant discharge in production sewage significantly decreased in Longchuan locomotive depot. The annual discharge amount of oil, COD, SS would reduce 21.9 kg, 76.1 kg and 145.3 kg, respectively. Moreover, the annual emission amount of CO, NOx, SO2, soot and CnHm would reduce 153.21 t, 1 085.42 t, 47.47 t, 328 t and 110.06 t, respectively because electric traction was applied. The electrification reconstruction project of Guangzhou-Meizhou-Shantou railway would bring great ecological, economic and social benefit to the regions along the railway.
