—To effectively achieve mitigation of heat island
effects requires classification of urban climate zones in advance
based on analysis of the relationship between air temperature
and urban spatial elements. The objective of this study is to: 1)
identify influential urban spatial elements affecting air
temperature by statistical analysis, and 2) provide fundamental
information on establishing thermal environment enhancement
planning through urban climate zones (UCZ) based on statistical
This study consists of three parts: First, the air temperature
of study area was analyzed using Lands at TM remotely sensed
images. Next, preparative variables including topology land use,
land cover, building types, and human activities to classify UCZ
were prepared, and influential urban spatial elements affecting
air temperature were identified by regression analysis. Finally,
UCZ were delineated by K-clustering analysis, and the
appropriateness of the classified UCZ were verified using
The study results show that urban elements affecting air
temperature include impervious surface ratio, elevation, water
area, distance from a subway station, and road area. In addition,
a total of 10 UCZ were detected by K-clustering analysis, and
the results of the ANOVA test shows that each classified UCZ
was in statistically different groups. Moreover, UCZ and air
temperature maps were found to display an almost identical
This study identified more accurate and clearer UCZ
boundaries and explained statistically significant urban spatial
characteristics to better understand the urban climate
phenomenon. The results of this study can provide urban
planners, architects, and landscape planners fundamental
information to help manage the urban thermal environment.
