摘　　要：从系统的角度界定了循环经济和矿区循环经济的内涵,提出了煤炭矿区循环经济系统的基本框架,并以能值分析法为基础构建了矿区循环经济系统生态效率评价指标体系与方法。运用所构建的评价指标体系与方法对山东某矿区进行了研究,得出该矿区循环经济系统2007—2011年5年间的能值效率变化趋势图和生态效率指数趋势图,研究结果与该矿区的实际发展趋势基本一致。表明运用能值分析法所建立的评价指标体系具有较强的有效性,并且对煤炭矿区发展循环经济、提高生态效率具有重要指导意义和参考价值。This paper takes the recycling economy as a theoretical basis and systematically defines the recycling economy and recycling economy of coal mining areas. A basic framework for the recycling economy system in coal mining areas is put forward and a brief analysis of its systematic features is carried out. The author proposes that this is a complex interrelated system involving elements such as the environment, economy, resources, population, science, technology and culture. This paper starts with current problems faced by coal mining areas in China. By looking into the results of research and related references in this field from home and abroad, this paper briefly describes the basic rules and steps of Emergy Analysis and constructs an evaluation system for the eco-efficiency of the recycling economy in coal mining areas. It first sets up an emergy flow evaluation criterion which entails emergy efficiency evaluation criteria, sustainable development index and eco- efficiency index making it possible to analyze and study the sustainability and eco-efficiency of the recycling economy system in coal mining areas. By adoping this evaluation system, the paper carries out empirical research on a coal mine in Shandong province. By looking up statistical yearbooks, coal mine data and empirical surveys, an emergy data chart for the recycling economy system of this mine and an emergy evaluation chart will be presented. On this basis, the author drafted graphs of the variation tendency in emergy efficiency and eeo-efficiency index in the five years from 2007 to 2011. Two tables have been devised and the predicted result is basically consistent with the real trends developing in the coal mining area. Finally,the author proposes that for future development, the proportion of investment in the environment should be increased while improving its overall investment so as to realize a coordinated development between the economy and environment, prolonging the useful years of the coal mine and improving the sustainability of the r
