基于循环经济的低碳农业建设路径研究

A Study of Low-carbon Agriculture Based on Circular Economy Thought

低碳农业是一种以低能耗、低污染、低排放和高效能、高效率、高效益为主要特征,以较少的温室气体排放获得较大产出的全新的农业发展模式,它与发展农业循环经济相辅相成。以规模养猪场实施沼电工程为例,研究了基于循环经济的农业温室气体减排效益。结果显示,以循环经济理念为基础的沼电工程的实施,可以降低农业生产的温室气体排放,是发展低碳农业的重要手段。

Low-carbon agriculture is a kind of agricultural industry which has lower carbon-emission and higher performance and effiiency. Due to its huge GHG emission in global climate change, it has signif/cant meaning to create a new model of developing agricul- tural industry with the goal of low carbon emission. In this paper, a hypothetical case was studied, which was a livestock farm with a capacity of 10000 pigs. By developing the CHP biogas plant, we can reduce CO2 emission with 15900 tons per year. The conclusion shows that it is meaningful for the stakeholders to develop lower carbon agricultural industry based on the circular economy thought.
