摘　　要：在对三峡库区自然环境及生态农业发展存在问题分析的基础上,运用类比方法估算了三峡库区农业系统温室气体的排放量,结果显示2008年三峡库区耕地CO2,CH4,N2O的排放量分别为10,7,0.5万t/a。在此基础上进一步提出了山地综合立体开发模式、立体生态渔业养殖模式、水土流失综合防治模式、特色循环生态农业复合模式4种低碳农业发展模式及相应的减排对策。Based on the analysis on the characteristics of natural environment and problems of circular eco-agricultural development,analogy method was used to estimate the agricultural system of greenhouse gas emissions in the Three Gorges Reservoir Area.The results showed that the reservoir area the amount of farmland emissions CO2 was 1.0×105 tons,CH4 was 7.0×104 tons,and N2O was 5.0×103 tons in 2008,respectively.Based on the estimation of greenhouse gas emissions from agricultural production of Three Gorges Reservoir Area,suggestions on low—carbon eco-agriculture development models of Three Gorges Reservoir area were put forward.These models include integrated mountain stereoscopic development models,three—dimensional ecological fishery breeding models,the prevention and control of soil erosion model,characteristics—based ecological agriculture circulation composite models and the reduction measures.
