台北盆地生態能量流動與土地使用之關係—(II)生態能量分區
1999
The convergence of energy flows will result in spatial pattern of urban hierarchy. In this paper, Taipei Basin is used as the case study area, and theory of energy hierarchy, developed by Odum, is used to analyze energy flows for the study of spatial urban pattern. The spatial data base of energy flows in energy units for the Taipei Basin, and the 1178 administrative districts in Taipei Basin are used as units for multivariate classification. As a result, 19 variables are condensed into four factors using principle component analysis. Factor scores of each administrative districts are then used as input for cluster analysis and discriminant analysis. Based on the input of different types of energy flow and the output of urban production and wastes, the Taipei Basin is classified into six energetic zones: mixed- use urban core; high-density urban residential district; service and manufacturing urban district; newly developed suburban district; agricultural district; and natural area. The calculation of transformity and emergy indices for each zone further establish the hierarchical order of the developed urban energetic system. Implication of the energetic classification to planning practice is also discussed to conclude this research.
