摘要
本文从食物全生命周期环节、温室气体类型、温室气体直接排放源三方面系统分析了1996-2010年我国食物全生命周期温室气体排放特征。从食物生产和消费角度,确定我国饮食结构的转变、化肥高投入的传统农业生产模式、食物损失浪费三大趋势是导致食物全生命周期温室气体排放增长的主要因素。并提出转变食物消费方式,实现营养均衡膳食结构,减少不必要的肉类消费;生产方式上逐步实现从传统农业向有机农业的转变;加强宣传引导,最大限度减少食物餐桌浪费,同时加强食物物流环节基础设施建设,将分销配销过程的损耗降至最低。通过食物生产和消费方式的转变与技术进步相结合的方式,构建出适于我国的绿色、低碳、可持续的农业生产和食物消费模式。
Greenhouse gases emissions of food life circle in 1996 -2010 were analyzed based on food life circle, greenhouse gas type and the direct source of greenhouse gas. This research concluded that change of diet structure, high-input chemical fertilizer agricultural activities and waste of food are the three major drive factors to the increase of greenhouse gas emissions. The paper also proposed the most sustainable ways to decrease the emission of greenhouse gas, which are to guide rational consumption by reducing the unnecessary meat consumption, to change the traditional agriculture to organic agricuhure, to strengthen the publicity guide by reducing the food waste and to enforce the infrastructure construction of logistics reducing food loses in distribution section. Establishing the green, low-carbon, sustainable agriculture and food consumption mode can be realized through combining the transformation of food production and consumption mode and technical innovation.
