横断面规划思想在城市更新中的应用——以广州新中轴南段城市更新方案为例

APPLICATION OF TRANSECT PLANNING IN URBAN REGENERATION: A CASE STUDY OF THE URBAN REGENERATION PROGRAM IN THE SOUTHERN PART OF GUANGZHOU NEW CENTRAL AXIS

分析传统规划方法在城市更新中所面临的困境.应用横断面规划的方法分析广州新中轴南段城市更新地区的形态特征,拟定各分区的发展愿景和规划策略.城市设计方案通过控制性规划定义为7种形态区划类型,编制形态条例作为城市更新的指引.强调横断面规划以形态分区为基础,提供了从现状形态分析到规划愿景设计再到形态条例的连贯性工作方法,把城市(社区)发展愿景转译为强制性的形态条例关键是要形成社会共识,该方法可适用于城市更新或“微改造”.

This paper starts with an analysis on the predicament of traditional urban planning method in urban regeneration, and analyzes the morphological characteristics of the urban regeneration area in the southern part of the new central axis of Guangzhou by using the transect planning method, before developing the development vision and planning strategy of each district. The urban design scheme is defined as seven types of zones through the regulatory plan, and the form-based codes are used as guidelines for urban regeneration. It is emphasized that transect planning is based on morphological zones and provides a coherent approach from the analyses of present state to the planning of the vision and to the formbased codes. The key to translating the urban (community) development vision into a regulatory form is to form a social consensus. The method can be applied to the urban regeneration or "microtransformation".
