应用能值分析理论与方法对陕西省商洛市农业生态经济系统的能值流进行了研究,通过计算典型能值指标,与其他地区进行了对比。分析结果表明:商洛市生产效率和开发程度较低,仍处于传统农业阶段,但是具有较强的可持续发展能力和开发潜力,因此,应增加农业系统的能值投入。

Analysis of Energy of Agricultural Eco -economic System in Shangluo City, Shaanxi Province

By using energy analysis theory and method,this paper studied the energy flow of the agricultural eco-economic system in Shangluo city of Shaanxi province,and compared the energy of this city with that of other districts through calculating the typical energy indexes.The analysis results showed that the production efficiency and development level were lower in Shangluo city,which was still at the traditional agricultural stage,but it had a strong capacity of sustainable development and exploitation potential.Therefore,the energy input must be increased in agricultural eco-economic system.
