| 摘要: |
| 城市群作为区域发展战略核心和经济建设的引擎，是城市间相互协同，发挥聚集效应一体化城市群体。城市代谢系统是城市发展过程中物质、能量、货币和人类劳动力综合协调的自组织系统。城市代谢系统失调被认为是导致城市人口负荷过载、城市环境污染严重和资源过渡消耗等城市可持续发展问题的主要原因，因而通过社会—经济—生态等多维度指标构建对城市群可持续发展评价尤为重要。本文以闽三角城市群为研究对象，基于能值分析方法结合城市代谢理论，从不同维度系统分析闽三角城市群能值代谢状况及可持续发展水平，并对不同城市群间和城市群内进行对比分析。研究发现：（1）2010—2017年闽三角城市群总能值总体呈现上升趋势，且不可更新资源能值比重增幅较大，表明经济发展以资源消耗为主，对城市群生态环境产生负面影响。同时，人口增长、土地空间限制和生态经济可持续发展之间存在一定矛盾。（2）从不同城市群之间对比来看，闽三角城市群与环太湖城市群在资源利用率和经济产出方面略有差距，但在能值货币比率和环境承载力等指标方面表现较好，反映出闽三角城市群社会经济与生态环境较为协调，生态文明建设取得较好效果。（3）从城市群内部结构对比来看，厦门、泉州、漳州三个城市均处于健康发展状态，且厦门、漳州可持续发展能力远高于泉州。厦门因产业结构优势对外部资源依赖性最小，总体经济发展效率稳步提升，较好实现了经济发展与城市社会福祉提高之间协调发展。泉州以第二产业为主导，经济产出效率提升较快但发展效率偏低，其社会经济发展对生态环境造成较大压力。漳州产业结构较为平衡，区位优势和自然生态环境为其城市发展提供了较大潜力。 |

| Abstract: |
| Background, aim, and scope As the core of regional development strategy and the engine of economic construction, urban agglomeration is an integrated urban agglomeration that cooperates with each other and exerts agglomeration effect. Taking Fujian triangle urban agglomeration, China as the research object, this paper evaluates the differences in the sustainable development level of Fujian triangle urban agglomeration as a whole and the ecological economic system among the cities, which provides reference and theoretical support for the formulation of sustainable development policies for the urban agglomeration. Materials and methods Based on the statistical yearbook, statistical bulletin and other physical geography and socio-economic statistical data, this paper adept the emergy analysis method to construct an emergy evaluation system for the metabolic system of urban agglomerations from the four dimensions of society, economy, ecology and sustainable development. Taking Fujian triangle urban agglomeration, which can represent emerging urban agglomerations, as the research object, this paper systematically evaluated its emergy metabolism and sustainable development level from 2010 to 2017, compared and analyzed different urban agglomerations and cities within the urban agglomeration. Results (1) From 2010 to 2017, the total energy of Fujian triangle urban agglomeration showed an overall upward trend, and the proportion of energy of non-renewable resources increased significantly. (2) From the comparison of different urban agglomerations, there was a slight gap between Fujian triangle urban agglomeration and the Taihu Lake in terms of resource utilization and economic output. (3) From the comparison of the internal structure of the urban agglomeration, Xiamen, Quanzhou and Zhangzhou are in a healthy development state, and the sustainable development ability of Xiamen and Zhangzhou was much higher than that of Quanzhou. Discussion Most of the previous studies have focused on a single province, city or country as the research object, and the evaluation of the sustainable development of urban agglomerations and the analysis of the synergy and trade-off relationship between cities within the urban agglomeration are relatively lacking. The research data used in this paper are mainly statistical data. Although the complex commodities have been dismantled and revised, there is still a gap with the actual impact of the emergy value of goods and services and their emission and pollution. In terms of horizontal comparison of different urban agglomerations, this paper only compared with the data in 2015, the stability of its conclusions needs to be further verified. In the comparison of cities within urban agglomerations, future research should simultaneously consider the independence and relevance of different cities. Conclusions (1) The economic development of Fujian triangle urban agglomeration is mainly based on resource consumption, which has a negative impact on the ecological environment of the urban agglomeration. At the same time, there are certain contradictions between population growth, land space constraints and sustainable development of ecological economy. (2) The social economy and ecological environment of Fujian triangle urban agglomeration are more coordinated, and the construction of ecological civilization has achieved good effects. (3) Due to the advantages of industrial structure, Xiamen has the least dependence on external resources, and the overall economic development efficiency has been steadily improved, better realizing the coordinated development between economic development and the improvement of urban social welfare. Quanzhou is dominated by the secondary industry, and its economic output efficiency has improved rapidly but the development efficiency is low. Its social and economic development has caused great pressure on the ecological environment. Zhangzhou has a relatively balanced industrial structure, and its location advantage and natural ecological environment provide great potential for its urban development. Recommendations and perspectives This paper believes that in the planning and construction of future urban agglomerations, planning should be co-edited and regional co-ordination; industry co-chain, technology-driven; ecological co-construction to reduce energy consumption; traffic co-network, resource sharing. |
