Research on the Coupling of Public Space Morphology and Summer Wind Environment in Qingdao’s Urban Villages

With the development of modern cities, people’s living environment requirements are constantly improving. Urban villages in the Qingdao area, as a key area for urban renewal, are affected by the sea breeze and have a warm and humid climate in summer, which, together with their problems of irrational layout and the poor ventilation of outdoor public space, seriously reduce the quality of public space. In order to improve the outdoor comfort and living quality of urban village residents, this study uses CFD numerical simulation and SPSS25 software analysis to investigate the coupled relationship between outdoor public space morphology and the summer wind environment in urban villages, and derives a range of values for public space morphology indexes to meet the needs of human comfort. The study found the following conclusions: a. The average wind speed ratio is negatively correlated with household profile density and enclosure and positively correlated with dispersion, and the degree of influence is in the order of enclosure > dispersion > household profile density. b. When household profile density is less than 0.5328, enclosure is less than 0.8228, and dispersion is less than 17.21, the percentage of comfort zone area in the urban villages increases significantly. The renewal and transformation of urban villages should be based on the interaction mechanism between public space morphology and wind environment in the urban villages, which provides a reference basis for improving the spatial quality of urban villages.
