China's cities are facing a new stage of refined stock construction. The fragmentation of the urban street landscape has led to some streets neglecting their important function of carrying out the public activities of citizens. The landscape weaving theory based on the concept of broken environment patching and connection has guiding significance for street landscape construction. The characteristics of the street landscape weaving theory were summarized, the street landscape images of 1098 streets in Harbin were analyzed by using Pyramid Scene Parsing Network (PSPNet), and the street landscape quality of Harbin was analyzed from the perspective of the landscape weaving theory. Finally, it is found that the intensity of changes between the building and sky interface, street enclosure, linear density, building visual factors, pedestrian roads, and the density distribution of various Points of interesting (POI) in the study area are similar, showing a distribution trend of high in the center and low around, However, the intensity of plant interface change, sky visibility factor, vegetation visibility factor, the proportion of traffic signs in the image, and the proportion of motor vehicle roads in the image are opposite. This study analyzes the distribution and intrinsic relationship between the theoretical features of Harbin's urban street landscape weaving and enriches the research system of landscape weaving theory, intending to provide some ideas for street landscape weaving strategies from an urban perspective.
