Abstract:

We used the nine metabolism systems of Fujian Province' urban as research object in this paper. According to the basic principles of urban metabolism, and the use of emergy theory and the interaction relationships analysis of urban metabolic systems, we do this distinction research from two aspects: one is ecological flow and the other is the interactions between socioeconomic system and the natural ecosystem of urban metabolism. Even more, some indexes and certain ranks were created by GIS technology. The results showed that: There is a clear difference of renewable resources emergy and the export-import emergy between coastal and inland areas while an obvious difference of non-renewable resources emergy between south and north areas; What's more, the natural ecological subsystems of Fuzhou, Xiamen, Quanzhou and Zhangzhou restricted the socioeconomic subsystems While the socioeconomic systems of Sanming,Quanzhou, Nanping, Longyan, Ningde and Putian exploited the natural ecological subsystems.
