Abstract
The expression and perception of cityscape has significance influence on the preservation and regeneration of heritage. However, due to the urban sprawl in urbanizing, a large number of commercial exploitation have resulted in a series of obstacles on the expression and perception of heritage features. In order to study the importance of the expression and perception of the heritage features on the cityscape, this paper selected a typical historical and cultural city Harbin in China as the research object. In the current work, the large-scale investigation of cityscape was analyzed on the basis of street view map auditing from a human point of view. The relationship of cityscape between the features of heritage and cityscape were investigated using the semantic segmentation of machine vision, and Harbin was taken as a case study to examine whether variations exist between different areas. Results showed a significant coupling in the current city between cityscape and features of heritage. Therefore, according to the results of the relevant analysis, the paper confirmed the key indicators of the perception and expression of heritage, and advances some urban planning strategies to avoid the negative effects that urban sprawl brings to cityscape on heritage. The results of this work will provide a comprehensive understanding of the preservation and regeneration of the heritage.
