Abstract

Compact cities and their urban forms have implications on sustainable city development because of high density urban settlement, increased accessibility, and a balanced land use mix. This paper uses quantitative means of understanding urban morphological characteristics with reference to the differing qualities of the urban form (i.e., street patterns, building volumes, land uses and greenery). The results, based on 89 neighborhood communities of Hong Kong, show varying degrees of regional differences in the urban built form supported by numerical statistics and graphical illustrations. This paper offers empirical evidence on some morphological characteristics that can be estimated objectively using modern geospatial technologies and applied universally to inform urban planning. However, more studies linking these quantifiable measures of the physical form with sustainable urban living are needed to account for human comfort in the totality of environmental, social, and economic responsibilities.

Highlights

  • Urban morphology describes the physical form of a city in terms of its building layout, road patterns, land uses, and green space [1]

  • This paper examines the implications of urban forms in 89 neighborhood communities of Hong Kong with reference to the effects of varying qualities of street patterns, greenery, building volumes, and land uses

  • It shows that Kowloon Peninsula (KLN) reported very high mean scores for 3 of the 5 regions of Hong Kong

Summary

Introduction

Urban morphology describes the physical form of a city in terms of its building layout, road patterns, land uses, and green space [1]. Studies have shown that the urban form of a city can affect air dispersion [4,5,6], induce urban heat islands [7,8], cause health and thermal comfort problems [9,10,11], and influence energy consumption [12]. Morphological differences within a built environment exist because of land use patterns and the varied neighborhood preferences of certain social groups [13]. Urban land uses containing tall buildings have significantly different and greater variation of morphological qualities compared to other urban land uses [14]
