- Abstract:
- Urban metabolism highlights the processes of materials, energy and money flows of urban system, which provides a new perspective on analyzing the process of urban metabolism of different functional cities. In this paper, in order to explore the similarities and differences of metabolic characteristics and variation rules of different types of resource-dependent cities, taking the capital Taiyuan of Shanxi Province and a traditional resource-dependent city—Jincheng as the example, respectively, we established the urban metabolic evaluation framework by employing a set of eight emergy-based indicators through using socio-economic data from 2007 to 2014, and compared the similarities and discrepancies from perspectives of the urban metabolic emergy system’s structure, emergy metabolic intensity, emergy environmental pressure and metabolic output efficiency. The results show that emergy system’s structure of Taiyuan is higher than Jincheng on the whole, emergy metabolic intensity of Jincheng is higher than Taiyuan, emergy environmental pressure of Jincheng is greater than Taiyuan, metabolic output efficiency of Taiyuan is higher than Jincheng. The recommendations on improving metabolic process of Jincheng and Taiyuan are put forward in order to lay the foundation for creatively solving metabolic resources and ecological risk, and to provide the scientific basis for ecosystem management of the city in Shanxi Province through comparative analysis.
