摘　　要：提出了区域循环经济发展必须满足三个基本条件,从产业链、物质循环、能量流动和生态环境承载力四个方面分析了循环经济指标体系,为环保部门项目审批和建设单位环境管理提供科学依据。产业链闭合指标采用生态网络化程度表示;物质循环指标包括单位产值物质需求量、人均物质消耗强度和物质生产力;能量流动指标包括净能值产出率、环境负荷率和环境负荷率;生态与资源承载力指标包括生态足迹和资源承载力。The three requirements of circular economy are summarized, and its assessment index system are also analyzed from four aspects of eco-industrial chains, material metabolism, energy flow and ecological carrying capacity. Eco-industrial chain closure is expressed by eco-industrial net. Material metabolism index include material demands per production value, average material expenditure and material productivity, energy flow index include net energy yield ratio, environmental loading ratio and energy index, and ecological carrying capacity include ecological footprint and resource carrying capacity.
