发展循环农业是低碳经济的重要途径

低碳经济是当前世界应对全球气候变化问题倡导的新的经济发展思路,农业节能减排是发展低碳农业的重大任务。本文认为发展循环农业是农业节能减排的重要路径。主要体现在:发展农田循环生产模式,增强农田碳汇功能,实现物质减量化投入,促进低碳农业发展;发展农牧结合循环模式,减少废弃物污染,提高牧业竞争力;发展农菌循环链,延长农田产业链,提高农民收入;发展复合生物循环模式,增加生物多样性,提高农业自然资源利用效率;发展农业企业循环产业模式,实现农业节能减排的工程化。

Circular agriculture as an important way to low-carbon economy

Low-carbon economy is a new developing economic thinking that responds to global climate change. In this paper, energy saving and emission reduction in agriculture is presented as an important low-carbon agriculture development method. This is mainly achieved through circular agriculture development. The ways of circular agriculture development in China includes enhancement of cropland carbon pools and cropland input reduction via developing circular production patterns. It is also an important way to develop combined circular pattern of cropping and pasture for reducing pollution from wastes and improving the competitive strength of pasture. Extending production chains in croplands and increasing farmer income via improving circular chains of edible fungi also make it viable. Meantime, a well developed circular agriculture increases biodiversity, improves the use efficiency of natural resources, enhances engineered energy saving and emission reduction. Developing circular industrial patterns and agricultural enterprises is another important way.
