摘　　要：传统能值足迹模型是评价循环经济发展水平的重要方法之一,该方法的提出虽然在一定程度上弥补了生态足迹模型的不足,但仍然存在缺陷。针对传统能值足迹模型变量取值范围过窄、核算口径不统一的问题,通过修正能值密度和能值承载力的核算变量提出改进能值足迹模型,并将其和传统能值足迹模型共同运用于南充市农业循环经济发展水平的测算以进行对比研究。研究表明,改进能值足迹模型较之传统能值足迹模型,能值密度核算时变量取值范围更全面,更能体现环境和技术变化对南充市农业循环经济发展的影响,而生态承载力的测算结果也更切合南充农业循环经济发展的实际,可以推知改进能值足迹模型是评价区域循环经济发展水平的相对适宜的方法之一。The traditional emergy footprint model is one of the important methods to evaluate the development level of circular economy. Though the method makes up for the defects of the ecological footprint model to some extent, it is still defected. For example,the range of variable values is too narrow,accounting caliber is not uniform,and so on. The improved energy footprint model is to solve these defects by modifying the calculation variables of energy density and energy carrying capacity. Then,the traditional emergy footprint model and the improved emergy footprint model are used to calculate the development level of the agricultural circular economy in Nanchong. Through comparison,it has been found that the improved emergy footprint model has a more comprehensive range of variables when calculating emergy density,which can better reflect the impact of environmental and technological changes on the development of agricultural circular economy in Nanchong. And the calculation results of ecological carrying capacity are more suitable for the actual development of agricultural circular economy in Nanchong. Therefore,it can be inferred that the improved emergy footprint model is one of the relatively appropriate methods to evaluate the development level of regional circular economy.
