Measuring Street Green View Index Based on Dynamic Perception

A case study of streets in zhongshan district, Dalian

Abstract

Urban streets are an important space for residents' daily life, and their green visual level plays an important role in improving residents' travel and living environment. Therefore, the evaluation methods and means of street greening also need to be continuously refined and supplemented. From the perspective of dynamic perception, this article takes Zhongshan District, Dalian City as the research area. Firstly, a dynamic perception perspective street green view index measurement model was constructed by introducing indicators including green quantity, volatility index, and continuous index. Secondly, we selected some streets in Zhongshan District, Dalian City for the application of the measurement model, and obtained objective quantitative measurement results. Finally, we evaluated street greening combined with subjective perception surveys to verify the proposed indicators. The results indicate that green quantity are important factors affecting the visual quality of streets. Lower volatility index and continuous index can achieve better visual quality. The research has further improved the green space measurement method, providing scientific basis for the refined design of urban green spaces.
