项目摘要
Environmental impact assessment for beef cow-calf systems with grazing was conducted using the procedure of LCA. The environmental impacts of the system with grazing on abandoned cultivated lands were evaluated to be smaller than those of the housing system. If all beef cows under the housing system in the Chugoku region are changed to be managed with the yearlong grazing system (grazing on abandoned cultivated lands in spring to autumn, and on semi-natural grasslands in winter), 12,355 (t CO_2 eq) of greenhouse gas emission, 210 (t SO_2 eq) of acidification potential, 26.7 (t PO_4 eq) of eutrophication potential and 93.1 (TJ) of energy consumption will be reduced in an year.
采用LCA程序对放牧的肉牛-小牛系统进行环境影响评估。经评估,废弃耕地放牧系统对环境的影响小于住房系统。如果将中国地区圈舍制度下的肉牛全部改为全年放牧制度(春至秋在废弃耕地放牧,冬季在半天然草地放牧)管理,则可减少12,355(t CO_2当量)温室气体排放量,酸化潜势210(t SO_2 eq),富营养化潜势26.7(t PO_4 eq),93.1一年内将减少(TJ)的能源消耗。
