摘    要:应用能值理论与分析方法对衡东县农业生态经济系统进行能值投入产出状况、环境承载情况和系统的运行效果进行定量分析.结果表明:街东县农业发展水平相对较低,处于由传统农业向现代化农业的转型期;衡东县农业系统的能值投入率相对较低;环境负荷力高于中国平均水平;系统优势度较低.应进一步增加农业系统的能值投入,特别是科学技术和可更新资源的投入。

关 键 词:农业生态经济系统  能值分析  衡东县  可持续发展

Abstract:This article quantitatively analyzes the energy input-output condition, the environmental loading ratio and the operating effectiveness of Hengdong agricultural eco-eeonomic system by using an energy analysis method. The result shows that the development level of Hengdong agriculture is relatively low and the county is transforming from traditional agriculture to modern agriculture, that the energy input of Hengdong agri-ecosystem is also relatively low but the environmental loading ratio is higher than that of the average level in China, and that the degree of its system advantages is of an initial stage. Therefore, energy input should be increased to the system, especially the input of technology and renewable resources.
Keywords:agricultural eco-economic system  energy analysis  Hengdong county  sustainable development
