Life Cycle Environmental Impact Assessment of Winter Wheat in North China Plain

摘要: Life cycle assessment methodology is used to establish inventory of resource use and emission assess life environmental impacts winter wheat with two different management practices in Huantai county,a high-yielding grain production region North China Plain.The result shows that the significant are energy depletion,acidification,global warming aquatic eutrophication,with impact indices 0.139,0.126,0.093 0.060,respectively.The depletion global potentials mainly from energy-intensive fertilizers,the acidification potential results NH3 volatilization nitrogen fertilization SO2 at stage agricultural chemicals production,and eutrophication volatilization.The aggregate index RMP 0.032 comparison 0.063 for CMP.Therefore,reducing nitrogenous fertilizer consumption developing energy-saving clean fertilizers key points control Plain.
