摘  要:
应用H.T.Odum的能值分析理论方法,对江西省农业生态经济系统的能值流进行了分析。结果表明,2005年能值投入量为4.46×1022sej,能值产出量为6.21×1022sej,净能值产出率为1.00,环境负载率为0.61,可持续发展指数为1.63。江西农业处于传统农业向现代农业转变的转型期。为了促进江西农业的可持续发展,应加强系统的能值投入和农业基础设施的建设,增大农业的科学技术研究和推广力度,优化系统的能值投入结构,调整农业产业结构。

摘  要:
Based on the theory of emergy analysis created by H.T.Odum,the emergy flow of agricultural eco-economic systems in Jiangxi Province was quantitatively investigated.The results indicate that the solar emergy input,the solar emergy output,the net emergy output ratio,the environment loading ratio and the sustainability index in 2005 were 4.46×1022 sej,6.21×1022 sej,1.00,0.61 and 1.63,respectively.Jiangxi is now in the stage of transformation from traditional agriculture to modern agriculture.In order to promote the sustainable development of agriculture in Jiangxi,it was suggested that the emergy input and infrastructure construction of agriculture should be reinforced,which needed to increase the investment in agricultural science and technology,optimize the structure of the emergy input in the Eco-economic system and adjust the agricultural structure.
