Book excerpt: The main focus of this monograph is urban acoustic environment of urban spatial morphology.It provides in-depth evaluation and research on the correlation between urban spatial morphology indicator and urban acoustic environment using urban spatial morphology and urban space units. Furthermore, it conducts quantitative analysis and statistic evaluation to reveal the relationship between urban planning indicators and acoustic environment. It also provides optimized strategies from three aspects of urban planning, architecture and landscape respectively. It intertwines the quantitative research of both acoustic environment and urban morphology through in-depth analysis and urban microclimate simulation by using Cadna/A acoustic simulation software. It concludes the influencing mechanism of acoustic environment on urban morphology. It makes a valuable contribution for the research on urban environment and urban morphology.
