Abstract:

Land surface temperature (LST) is one of the most important indicators of the urban thermal environment. The aggravation of urban thermal environment effect is closely related to the substitution of urban underlying surface by impervious layer and urban development. The urban space grows rapidly and the building height increases. The building height is an important index to measure the spatial distribution of buildings in a region. The vertical characteristics of urban buildings are remarkable. This article is based on the Zhongshan District of Dalian city building and remote sensing data, by using the single window algorithm and correlation analysis method, variation of the surface temperature of 2007 and 2017 space in the study area. The correlation between land surface temperature and the height of the building. The results show that: 1) The minimum temperature in the 2007 and 2017 study area increases from 22.497℃ to 29.015℃, and the maximum temperature increases from 36.091℃ to 43.213℃. Owing to the sea reclamation and the establishment of the Donggang Sub-district, the temperature in the northeastern part of the study area increased significantly. The study area in the northern Jiefang Road, and along the south, Qingniwa-Tianjin Street business gathering area near the temperature increases significantly. 2) In 2007 and 2017, the buildings are mostly distributed in the north and central parts of the study area. The buildings in the north of the study area are relatively high, while those in the middle of the study area (along Jiefang Road and Zhongnan Road) are relatively low. The regional construction has increased the north of Zhongshan District and Qingniwa-Tianjin Street business gathering area near the building of district construction has increased significantly, the trend spread south. 3) The data of land surface temperature and building height are divided grid (30 m×30 m) and the correlation analysis of ground surface temperature and building height is carried out by bivariate correlation analysis method. In 2007 and 2017, land surface temperature and building height show low correlation, the correlation coefficients are 0.346 and 0.331, respectively. To a certain degree, the correlation between land surface temperature and building height is discussed.

Key words: land surface temperature, heat island effect, architectural vertical characteristics, building height, Zhongshan district of Dalian
