| 摘 要： | 利用生命周期评价(LCA)方法建立规模化养猪场系统能源消耗和污染物排放清单，对系统生命周期不同阶段环境影响进行评价，通过评价找出降低环境影响的方法。研究了四个环境影响类型：能源消耗、富营养化、全球变暖和环境酸化，得出各类型环境影响指数分别为8.38×10-3，1.91×10-3，9.80×10-3和2.01×10-2；将系统生命周期分成饲料原料生产、生猪饲养和废物处理三个环节，得出各环节环境影响综合指数分别为2.52×10-2，1.23×10-2和2.71×10-3。结果表明，饲料原料生产环节的环境影响最大，因此，减少氮肥的使用量并在生产过程中实施节能和清洁生产，是控制规模化养猪场生命周期环境影响的关键。

| Abstract: | Life cycle assessment (LCA) methodology was used to establish inventory of energy consumption and pollutant emission and to assess life-cycle environmental impacts of large-scale piggery, and then the way could be found for lessen negative environmental impacts. Four impact categories were investigated, including energy depletion, eutrophication, global warming and acidification, with the impact indices of 8.38×10-3, 1.91×10-3, 9.80×10-3 and 2.01×10-2, respectively. The life cycle was divided into three stages, i.e. feed ingredients manufacture, swine rearing and wastes disposal, with the environmental impact complex index of 2.52×10-2, 1.23×10-2 and 2.71×10-3, respectively. The results showed that manufacture of feed ingredients had the largest environmental impact. Therefore, reducing nitrogenous fertilizer consumption and implementing energy-saving and cleaner production in the production of fertilizers were essential to control the life cycle environmental impacts of large-scale piggery. |
