The Impact Of Selecting Different Airport Sites On The Urban Heat Island Effect: A Case Study Of Dalian, China

To study the influence of selecting different airport sites on the urban heat island effect, we retrieved the land surface temperature (LST) of Dalian's main urban area using the thermal infrared band from the Landsat-8 data and graded thermal field. The results show that the Dalian Zhou Shuizi International Airport in Dalian's main urban area belongs to the high temperature zone, which indicates that the airport is an important contributor to the urban heat island effect. Similarly, we studied the urban area of Osaka, Japan, and found that the average land surface temperature of Kansai International Airport, 5 km from the coastline, is far lower than the average temperature of Osaka Airport in Osaka's urban area. This result shows that an offshore artificial island airport can effectively reduce the urban heat island effect compared to a terrestrial airport, which is more favorable for the ecological environment of the city.
