能值分析方法的应用与展望

Overview of Application and Development of Energy's Analysis Method

不同种类、来源和形式的能量具有很大的等级差异,在对系统进行能量分析中不能简单将它们相加减,用一般能量单位更无从表达和衡量自然环境资源与社会经济的能量关系.能值理论与分析方法通过能值转换率,把能流、物流和货币流等综合起来,计算出一系列反映生态与经济效率的综合指标体系.因此,能值方法也成为联系经济学与生态学的桥梁,并且被广泛地应用于农业、工业、城市、经济、旅游等领域.文章论述能值理论与分析方法中的评价指标的改进、能值分析方法与其他模型方法相结合在实际案例应用中所取得的进展;同时也指出能值理论仍需改进的方面,探讨该理论未来的发展方向.

Due to various types,sources and forms of energy with different grades,it cannot be simply added or subtracted in energy analysis within systems,and the energy relationship between natural resources and social economy can not be well expressed in general energy units.The energy value theory and analysis method combine energy flow,logistics and currency flow through energy value conversion rate,and calculate a series of comprehensive index systems reflecting ecological and economic efficiency.Therefore,energy method is regarded as the bridge to combine the economy and ecology,and is widely applied to various fields,like agriculture,industry,urban,economy and tourism.Improvement of evaluation criteria of energy theory and analysis,and method of combination between energy and other models in the case study have been introduced.Additionally,the article also points out the weakness of energy and explores its future development and direction.
