近年我国对城市高密度背景下的公众健康问题给予了大量关注，但相关研究主要以城市空间的物理密度作为出发点，对于感知密度的关注严重不足。本文梳理了感知密度的概念与研究现状，展示了感知密度的内涵与重要价值。在内涵上，感知密度的概念揭示了人对于空间密度的感知并非仅由物理环境所决定，还会受到社会文化背景与个人特质的影响。它能够使城市密度由单一的物理空间维度拓展至主观认知维度。在价值上，感知密度不仅会影响居民的身心健康，其丰富的影响要素也能够为高密度城市的可持续发展提供新的思路与方法。最后，基于对过往研究内容、手段、对象、场景的分析，笔者提出了我国背景下感知密度领域目前仍待研究的6 个重要问题。

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.
