Abstract: In recent years, the micro-transformation mode, which is based on preserving the main status quo, has been proposed. The influence and effectiveness of the micro-transformation mode are constantly being disputed and discussed. Enning Road in Guangzhou is a historic district with profound cultural heritage in Xiguan, and its regeneration program has always been a research hotspot. It is believed that visual material can convey spatial practice experiences beyond language, by which people can explore the metaphor of space. Visual methodology combined with content analysis, semiology and measurement of emotion had been used to study the spatial perception of the micro-transformation space in Enning Road. The main goal is to explore the influence of the micro-transformation mode and attempt to reveal the spatial perception mechanism of historic district transformation. The study result shows that the perceived intensity of micro-transformation area is the highest. The satisfaction of basic needs offers good emotional experience. And the participatory festival activities can enhance the perception of the district. While the texture maintenance and cultural details of the buildings can preserve the sense of history and trigger the emotion of nostalgia. However, under the influences of the micro-transformation, like historic district’s material substitution and function transformation, the involvement of extraneous elements in spatial perception practice leads to changes in cultural code and different spatial perceptions. This study attempts to use the content analysis method to refine the visual perception traits, and quantify the differences of spatial perception before and after the transformation in way of emotion measurement. In addition, the study adopts new methods in the field of spatial perception.

摘要： 历史街区改造是城市存量规划背景下的重要研究议题，近年来以保留现状格局为主的微改造模式被提出，目前其影响和成效被不断地争议与讨论。广州市恩宁路是具有深厚西关文化底蕴的历史街区，采用视觉方法结合内容分析、符号学及情绪评价解读其微改造空间的感知构筑，探讨微改造模式的影响，并试图揭示历史街区改造的感知建构机制。研究表明，微改造片区的感知强度最大，基础需求的满足实现了良好的情绪体验，参与型节庆活动能提升街区的感知度，而肌理维持和文化细节保留能进行历史感传递，促进怀旧情绪的触发。然在微改造模式的材料替换、功能转化等影响下，外来元素介入到感知实践中，导致文化符码和感知构筑的变动。本文尝试在采用内容分析法对视觉感知特质提炼的基础上，以情绪评定形式进行改造前、后感知差异的量化探讨，在空间感知的研究领域进行新方法实践。
