摘要: |
农业提倡低碳是历史的必然。提倡低碳必须符合适度、合情、合理的原则,避免极端化。中国农 业的特点是人多地少,必须实行高产高效与资源环境兼顾的集约持续农作制,不可盲目地推行所谓“农业 低碳化”。该文根据作者多年的实践研究以及国内外考察,围绕着如何适度合情合理提倡低碳的问题,对 涉及碳流的4个主要领域,即农作制、施肥、耕作和造林,进行具体的分析与讨论。 |

Abstract: |
Low carbon agriculture is a historical necessity. However, it should conform to the reasonable principles and avoid extremalization. Chinese agriculture with a big population and shortage of cultivated land needs to imple- ment the intensive sustainable farming systems that combined high yield with environmental protection. What is called”agriculture low-carbonization” should not be recommended blindly. Based on the author's practice and on-the-spot investigation both in domestic and foreign countries, the relationship between low carbon expenditure and four main agricultural activities, i.e., farming systems, fertilization, tillage, and forestation, were analyzed and discussed. |
Key words: low carbon expenditure low carbonization agriculture appropriately low carbon farming system no-fertilizer agriculture minimum tillage acting appropriately forestation and low carbon expenditure |
