摘　　要：为了更加清晰地说明天津市经济系统的资源利用及配置结构,为天津市今后的决策和发展方向提供依据,论文将三元相图法应用到能值分析中,对天津市经济系统的能值指标进行分析,并与北京、辽宁等几个省市的能值现状做了对比分析。对天津市近几年的能值相图分析表明,天津市的资源利用比例总体变化不大,外界能值的投入增多是天津市资源利用比例发生变化的主要原因;从天津市自身看,其资源利用结构分配向不合理状态发展,能值可持续性指数呈降低趋势。与其他省市相比,天津市的总体发展潜力比较大,在物质生产和服务业发展的水平较高,资源利用较为充分。天津市在发展经济引入外部资源的同时应注意开发和使用本地资源,提高天津市的经济可持续性。To more vividly and clearly demonstrate the resource utilization and its structure in Tianjin, emergetic ternary diagrams were introduced and analyzed in this paper to support govern- ment decision and urban development planning, and were compared with Beijing, Liaoning and other provinces and cities. The resources metabolism process of the eco-economic system can be studied with emergetic analysis, and all the emergetic indicators can be illustrated in a ternary di- agram （namely emergetic ternary diagram） which makes them simpler and straighter to under- stand. The emergetic ternary diagram made the emergetic theory more scientifically significant and made the development characteristics and existing shortages of different regions more obvious. The emergetic ternary diagrams of Tianjin from 1998 to 2005 showed that no great change happened in the total utilization proportion of resources, and the main reason of this change was investment feedback from outside of the system. As for Tianjin itself, its resources distribution structure has been developing in an unreasonable way with emergy sustainability index becoming lower and low- er over studied period. Compared with other cities and provinces in China, Tianjin had greater potential in its renewable resources development, remaining a high level in its material and service production. Attention should be attached to the development and exploitation of local resources when absorbing foreign capital, which can be used to drive local resource consumption and to im- prove economic sustainability of Tianjin.
