Under the call of the construction and quality improvement of urban space, the current uneven quality of the space caused by extensive urban development is worthy of attention, given the lack of maintenance of the old city core, the brown filed and vacant land, as well as the decay of the urban environment that is common in many cities. Drawing on a concept from sociology, this phenomenon of poor space quality and chaotic space order is defined as a physical disorder of urban space. With a new method of off-site built environment audits based on street view images, this study measures and evaluates the physical disorder of urban space within Beijing's Fifth Ring Road area. It finds that varying degrees of physical disorder is spread in this area, where the disorder has reached 50.1% among the 70,436 street points. The unkempt façades of buildings and roads lacking maintenance were the main factors of disorder that affect the quality of urban space in Beijing, leaving a negative impact on the vitality of the space. This study also carries out spatial intervention experiments that target specific disorder factors and can significantly improve the space. The large scale measurement of public spaces of poor quality or even disordered space provides an important basis for refined management and intervention of cities in the future.
