| 摘 要： | 应用生命周期评价方法,对辽宁西部地区建平县两种玉米生产方式进行生命周期资源消耗与污染物排放清单分析,在此基础上进行了生命周期评价.结果表明:水浇地玉米生命周期环境影响大小依次为:土壤毒素、寓营养化、全球气候变暖、环境酸化和能源耗竭,环境影响指数分别为0.69,0.19,0.013,0.011,0.000023;坡耕地玉米生命周期环境影响大小依次是:富营养化、全球气候变暖、环境酸化、土壤毒素和能源耗竭,环境影响指数分别为0.087,0.0055,0.0046,0.00055和0.00015.土壤毒素和富营养化主要来源于高耗能的有机肥和化肥的施用.因此,完善水浇地水肥管理,提高玉米肥料和水分利用率,加强坡耕地生态建设,保持水土、提高土壤肥力是降低建平地区玉米生产生态负荷的关键.
