Associations between summer wind environment and urban physical indicators in commercial blocks based on field measurement and simulation in Xi'an

As a major driving force to improve economic output, commercial blocks also play significant role in enhancing urban vitality. Due its characteristics of high building density and large volume, many wind environment problems are likely appear blocks. In this research, we simulated the four theoretical block models real STREAM software. The results suggest that under same other conditions, speed inside is lowest when footprint ratio reaches about 56%. When greater than 56.3% gradually increasing, or less 39.1% decreasing, both around will be steadily increased. addition, found quantitative correlations between physical indicators, such as mean height, stagger height enclosure degree, according which proposed adjustment strategies spatial form Finally, used cases verify effectiveness these optimizing
