This book focuses on the urban wind environment of urban center district. Through urban spatial morphology and urban space units it provides in-depth evaluation and research on the correlation between urban spatial morphology indicator and urban wind environment. Based on urban spatial morphology indicators, such as building density, FAR, average building height and wind environment parameter, it conducts quantitative analysis and statistic evaluation to acquire the influence relationship between urban planning indicators and wind speed. In addition, based on the 13 typical urban morphology units it also analyses the different situation of wind environment. Finally it provides the optimized strategies on urban planning, architecture and landscape. It intertwines the quantitative research between wind environment and urban morphology through in-depth analysis and urban microclimate simulation. It makes a valuable contribution for the research on urban environment and urban morphology.

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.

A major objective of this monograph is to identify the impact of thermal environment on urban center district. It provides in-depth evaluation and research on the correlation between urban spatial morphology indicator and urban thermal environment. In addition, the distribution characteristics of thermal environment and urban morphology units sample are also evaluated intensively. Furthermore, it analyses from three aspects of urban planning, architecture and landscape respectively and includes 35 concrete measures that could be brought into practice on reducing negative impact of urban thermal environment. Through 500 vivid figures, graphs and diagrams it illustrates the relationship between urban morphology and urban thermal environment. The analysis software employed by the author includes Ecotect, ENVI-met and Ray-man. It intertwines the quantitative research of both thermal environment and urban morphology through in-depth analysis and urban microclimate simulation. It makes avaluable contribution for the research on urban environment and urban morphology.

This book presents the latest research results related to urban center and urban center. It expounds the theoretical connotation, development models, hierarchical function, and spatial layout of the urban central structure through over 200 figures and tables. In addition, it analyzes the threshold characteristics, structural hierarchy, spatial characteristics, and development rules of urban central structure through field research and quantitative researches on the major urban central structures in Asia. Meanwhile, how to solve the issue of construction and layout of urban central structure in planning and design practice is also covered. The book reveals the laws and spatial characteristics of urban central structure and provides a valuable guide both for urban designers and planners as well as researchers and students working in urban design and planning fields. It sheds new light on better understanding of the urban central structure.
