摘要
导致全球变暖的温室效应气体尤其是CO2、CH4在大气中大量增加的最根本原因是化石能源的大量燃烧、森林极速破坏和农业生产活动。低碳农业是把大量的碳"扣押(sequestration)"在农业土壤和植物中,被认为是抵消人类碳释放的可能途径。改变原有的农业生态系统管理措施,大力建设和推广中国生态农业模式和技术,引导低碳化消费新潮流,是实现低碳农业的最根本途径。文章还提出"绿色"、"蓝色"、"白色"和"灰色"等低碳农业技术体系。
The atmospheric CO2 concentration is increasing due primarily to fossil-fuel combustion, quick deforestation and agricultural activities by human being.The low carbon agriculture (LCA) which sequesters atmospheric carbon in agricultural soils and plants is being advocated as a possibility to partially offset fossil-fuel emissions.The realization of the LCA requires a big change in agro-ecosystem management practices, the development of Chinese Eco-agriculture patternandtechnologies andguidance to the "low carbon"consuming style.Finally, the authors putforward the"Green", "Blue","White"and"Gray"technologicalsystemsfortheLCA.
