Perceived Density in Urban High-density: Concept, Value and Important Research Issues
Abstract：
In recent years, Chinese scholars have paid a lot of attention to public health issues in urban high-density, but related research mainly focuses on the physical density of urban space, and there is a lack of attention to perceived density. This paper summarizes the concept and research status of perceived density, demonstrating its connotation and important value. Perceived density reveals that human perception of spatial density is not solely determined by the physical environment, but is also influenced by social and cultural backgrounds and personal traits, which can expand urban density from a single physical to a cognitive dimension. In terms of value, perceived density not only affects the physical and mental health of residents, but its rich influencing factors can also provide new ideas and methods for sustainable development of big cities. Finally, based on the analysis of past research content, methods, objects, and scenarios, the authors propose six important issues that still need to be studied in the context of China.
