With improvements and optimization in the field of urban construction and people's pursuit of a higher quality of life, spatial quality has become an important aspect of urban research. However, rapid developments in the Chinese economy in recent years have caused disordered local urban space. In this study, area within the second ring of Hefei City was used as the research object, and multi-source data (e.g., street view images) were applied as carriers. On this basis, the physical disorder phenomenon, the relationship between different street types and the degree of physical disorder in Hefei City were explored through technical methods such as virtual built-environment audit. For area within the second ring road of Hefei City, the results revealed as following: (1) for the overall spatial quality, the degree of physical disorder was 35.11%; (2) among the spatial features explored, the commercial elements along the street presented the highest disorder degree; and (3) the quality of the space along the streets of land servicing commercial-industry facilities (Class B) was the worst, while the quality along the streets of logistics and storage land (Class W) was the best. Based on physical disorder theory, this study quantitatively measured the quality of street space. In practice, these findings provide important insights toward improving the urban management of cities in the future. In theory, they address the limitations of current research into physical disorder in China's urban space.
