چکیده انگلیسی
Water bodies are considered an effective factor in mitigating urban heat island (UHI) effects in large cities. In Chongqing, the largest city in western China, using Landsat 8 data obtained in the daytime during the summer, we analyzed the potential influence of the cooling effects of water bodies on the urban land surface temperature (LST) based on the gradient of the distance to the water bodies (DIST). The results indicate that the cooling effect of water bodies can reach one kilometer (horizontal distance) and have a great impact on the relationship between the urban form factors and LST, particularly at a DIST less than 500â¯m. The sampling was performed in a 250â¯mâ¯Ãâ¯250â¯m grid size, and correlations between four urban form factors (i.e., sky view factor, building density, mean building height and floor area ratio) and the LST gradually increased as the DIST increased. According to the multiple linear regression model, the DIST is an important independent variable at a DIST less than 500â¯m. This study may help researchers better understand the influence of urban form factors on thermal comfort considering water bodies.
