碩士 === 國立中興大學 === 資源管理研究所 === 86 === The rivers and human civilizations have been closely related duringhistory. As a consequence of rapid growth and changing economy, people utilize water and riparian land intensively. However, the demand-oriented resource use may not be a sustainable future. Energy is a key force that can effect the pattern of landscape and cultural evolution. Energy-environmentrelation is also regarted as a major factor for a sustainable society. Consideringviewpoint of ecological energetic is a suitable way to discuss the implication for symbiosis between river and city.This thesis reviews the mutual effects between river and landuse to develop the conceptual system model, and applies the theory of emergy analysis and energy hierarchy to analyze the energetic spatial pattern of 6subsystem. Then, this theis identifies the energetic hierarhy formed by the spatial energy flows. As a result:(1)the caculation of river energy distribution and emergy indices establish the same hierarchical order as Strahlar''s stream order;(2)the caculations of economic management inputs establish a similar hierarchical order as land-use pattern; and(3)the implication of these two different spatially energetic hierarchy indicates a better implication to planning practice for organizing a systm in a sustainable way.
