Abstract
This paper aims to identify the relationship and relative importance of the elements in a Green City planning, which are based on the spatial restructuring for qualities of urban form such as accessibility, efficiency, viability, security and amenity and the physical restructuring of the fabric and metabolism at various scale of urban system. What we find is that the linkage between quality of spaces in urban form and its planning elements (of a Green City) are generally complex and indirect. With these considerations, we find out the planning directions and practical lessons through pairwise comparison matrix of 'quality of spaces (Q)' and 'planning elements(G)' using the AHP(Analytic Hierarchy Process). Also, this paper describes how to define impact on restructuring of urban system by connection between quality based goals-quality of spaces (Q), strategy planning-planning elements (G) and performance indicator-planning indicator (T) in urban system by applying QFD(Quality Function Deployment) methodology. The analysis in this paper is completed by the following processes: i) extracting major components on quality of spaces(Q) the planning elements(G), ii) understanding the co-operative relationship or effects between them, iii) analyzing the relative importance of planning elements with relation to quality of spaces, iv) and then determining the impact on planning elements by performance indicator in relation to quality of spaces implicated in urban system. It thus draws implications for spatial and physical restructuring of urban system at various scale in the planning process for a Green City. Finally, it is very important for an urban system as an engine of a city to be tuned or re-engineered for greater efficiency with good match or linkage between planning elements in relation to its qualities of urban space.
