題名 Quantifying Urban Form: Compactness versus ‘Sprawl’ 作者 蔡育新
Tsai, Yu-Hsin貢獻者 地政系 日期 2005.12 上傳時間 15-Sep-2014 14:42:34 (UTC+8) 摘要 This paper develops a set of quantitative variables to characterise urban forms at the metropolitan level and, in particular, to distinguish compactness from `sprawl`. It first reviews and analyses past research on the definitions of urban form, compactness and sprawl, and corresponding quantitative variables. Four quantitative variables are developed to measure four dimensions of urban form at the metropolitan level: metropolitan size, activity intensity, the degree that activities are evenly distributed, and the extent that high-density sub-areas are clustered. Through a series of simulation analyses, the global Moran coefficient, which characterises the fourth dimension, distinguishes compactness from sprawl. It is high, intermediate and close to zero for monocentric, polycentric and decentralised sprawling forms respectively. In addition, the more there is more local sprawl, composed of discontinuity and strip development, the lower is the Moran coefficient. 關聯 Urban Studies, Vol.42, No.1, pp.141-161 資料類型 article dc.contributor 地政系 en_US dc.creator (作者) 蔡育新 zh_TW dc.creator (作者) Tsai, Yu-Hsin en_US dc.date (日期) 2005.12 en_US dc.date.accessioned 15-Sep-2014 14:42:34 (UTC+8) - dc.date.available 15-Sep-2014 14:42:34 (UTC+8) - dc.date.issued (上傳時間) 15-Sep-2014 14:42:34 (UTC+8) - dc.identifier.uri (URI) http://nccur.lib.nccu.edu.tw/handle/140.119/69901 - dc.description.abstract (摘要) This paper develops a set of quantitative variables to characterise urban forms at the metropolitan level and, in particular, to distinguish compactness from `sprawl`.
