摘要
农业生态经济系统是由农业生态系统和农业经济系统紧密嵌合而成的特殊的人工-自然复合系统,是人地关系地域系统研究的主要对象之一,也是关于现代生态经济研究的核心主体之一。文章论述了能值理论内涵与方法,基于CNKI与Web ofknowledge数据库的文献分析表明,能值理论在中国农业生态经济领域研究具有普遍的认可度;能值研究在基础理论阐释、指标体系开发、案例实证研究等方面取得了进步,但也存在一些急需解决的关键问题,主要包括农业能值流程图的绘制,农业能值强度的区域适用性,农业能值计算的时空比较研究等三个方面。
Agro-ecological economic system is a kind of a special complex artificial-natural system coupled by the agro-ecosystem and the agricultural economic system,which is also one of the main targets studied in the field of regional human-natural relationship,and the central agent of research on ecological economics.This paper briefly discusses the concept and framework of emergy theory,and then,by literature analysis based on the database of CNKI and Web of knowledge,we concluded that the emergy theory has universal recognition in the field of agriculture,and presents an increasing trend.The emergy theory applied in Agro-ecological economic system research makes some progress in the field of basic theory research,indicators development and empirical studies.However,there are also some key issues that need to be resolved,including agricultural emergy flow diagrams,regional applicable of emergy theory,and comparative research on space-time scale.
