| 摘 要： | 温室气体排放引起的全球气候变暖是人类关注的环境热点问题之一。本文从农业生态系统影响全球变暖的主要温室气体(CO2、N2O 和CH4)的产生和排放出发, 探讨有机农业在生产减排和土壤固碳方面的机理。研究发现相对于常规农作而言, 有机农业在减排和固碳方面具有很大优势和潜力; 然而, 从长期来看, 通过土壤固碳减少大气温室气体的排放不是无限制的, 到一定程度后会达到一个平衡。因此, 更多的有效固碳途径和管理措施有待于进一步研究。同时, 从低碳理念出发, 强调中国加强有机农业环境效益研究的必要性。 |
| 关 键 词： | 有机农业 温室气体 低碳 土壤固碳 |

| Abstract: | Global warming due to the greenhouse gas(GHG) emissions is one of the most serious environmental issues.From the perspectives of CO2,N2O and CH4 emissions in agriculture,this paper reviewed several studies and compared conventional and organic agriculture performance in the light of GHG emissions and soil carbon sequestration.Compared to conventional agriculture,there were less energy demand,high CO2 abatement and soil organic carbon(SOC) sequestration in organic agriculture with large scale adoption.Howeve... |
| Keywords: | Organic agriculture Greenhouse gas Low carbon Soil carbon sequestration |
