福建省地级市代谢系统差异性研究

以福建省9个地级市的代谢系统为研究对象，根据城市代谢的基本原理，运用能值理论和城市代谢系统互动关系分析方法，从代谢系统生态流和代谢系统中自然子系统与社会经济子系统之间的互动关系这两个方面对9个地级市代谢系统差异性研究，并结合GIS技术对其结果进行等级划分和空间差异性比较。结果表明代谢系统的可更新资源能值投入和进出口能值存在明显的海陆差异性；代谢系统的不可更新资源能值投入存在明显的南北差异性；福州市、厦门市、泉州市和漳州市这4个地级市代谢系统中自然生态子系统对社会经济子系统存在着限制关系，三明市、南平市、龙岩市、宁德市和莆田市这5个地级市代谢系统的社会经济子系统对自然生态子系统存在掠夺关系。

The distinction research in urban metabolism system of Fujian Province

We used the nine metabolism systems of Fujian Province＇s 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 did this distinction research from two aspects： one was emergy flow and the other was 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 was 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.
