城市形态适应性研究——以拉萨为例

Study on the Adaptability of Urban Form--A Case of Lhasa

本文以城市形态类型学理论为基础,对分形城市、国内外城市结构进行概述,提出城市形态的影响因素、指标与演变动力。通过进一步研究拉萨城市形态,从宏观角度分析其选址、演变、老城区与新区对比等;从微观角度分析其空间构成要素,如公共空间、城市肌理、视觉序列、建筑等。最后提出城市形态适应性策略。

Based on the theory of urban morphology typology,this paper gives an overview of fractal city and urban structure at home and abroad.The influencing factors,indexes and evolution dynamics of urban form are put forward.The urban form of Lhasa is further studied,and its site selection,evolution,and comparison between the old city and the new city are analyzed from a macro perspective,and its spatial components,such as public space,urban texture,visual sequence,architecture,etc.are analyzed from the perspective of microcosmic view.Finally,the adaptive strategy of urban form is proposed.
