生命周期评价在玉米种植及深加工产品中的应用

对LCA在玉米种植环境影响研究中的目标与范围定义、清单分析、环境影响指标与计算方法、结果解释等方面的研究进行了梳理分析，其中大部分文献均对碳足迹进行了计算，CML（Institute of Environmental Sciences of the University of Leiden）、ReCiPe（许多LCA领域研究人员共同开发）和IPCC（Intergovernmental Panel on Climate Change）方法是应用最多的3种方法，经分析计算得到国外玉米种植单位产量碳足迹均值为0.50kg CO₂-eq/kg，我国的均值为0.58kg CO₂-eq/kg.同时本文也对LCA在玉米深加工产品中的研究进展进行了分析整理，对今后LCA应用于玉米种植及深加工产品中的发展方向进行了展望.

Application of life cycle assessment in maize planting and deep processing products

This paper focused on the research of Life Cycle Assessment (LCA) in the environmental impact of maize planting, including the definition of goal and scope, inventory analysis, environmental impact indicators and calculation methods, results interpretation and so on. Carbon footprint was calculated in most literatures. CML(Institute of Environmental Sciences of the University of Leiden), ReCiPe (developed by many LCA researchers) and IPCC (Intergovernmental Panel on Climate Change) are the three most widely used methods. Through analysis and calculation, the average carbon footprint per unit yield of corn planting in foreign countries is 1.78kg CO₂-eq/kg, while that in China is 1.31kg CO₂-eq/kg. Meanwhile, this research also reviewed the research of LCA in deep processing products from maize, and prospects the development direction of LCA in maize planting and deep processing products in the future.
