Abstract:

Based on Dalian urban building data, SPOT 5 and Landsat 8 remote sensing data, using local climatic zone classification and land surface temperature inversion method to study the regional zoning types and characteristics of Dalian, and the impact of different local climatic zones on urban surface temperature. The research results show that the height of building types in Dalian are mainly low-rise buildings, multi-storey buildings and medium-rise buildings. The building density is medium density and high density. The Ganjingzi District is distributed with a large number of forest green areas, and the Zhongshan District is rich in park green space. The surface temperature is generally high, and the space is east to west and low. The surface temperature of more than half of the area reach 28~31℃, and the surface temperature of more than 1% is greater than 38℃, indicating that the region has extreme high temperature. At the same building height, the higher the density of the building area, the higher the surface temperature; the same density building, the multi-storey building coverage area has a higher surface temperature. The surface temperature of forest green space is the lowest, the surface temperature of park green space and community green space is almost the same, and the surface temperature of the auxiliary green land is the highest.

Key words: building environment, green space environment, urban heat island, local climate zone, land surface temperature
