Urban heat island density and occurrence are closely related to land use/land cover and land surface temperature variation. The effect of UHI can be described quantitatively with the urban thermal area variance index. This study aims to evaluate the UHI effect of the city of Samsun with the UTFVI index. LST data from 2000 ETM + and 2020 OLI/TIRS Landsat images were used to analyze UHI. The results showed that the UHI effect increased in Samsun's coastline band in 20 years. As a result of the field analysis made from the UTFVI maps created, in 20 years, 84% decrease in the none slice, 104% increase in the weak slice, 10% decrease in the middle slice, 15% decrease in the strong slice, 8% increase in the stronger slice, and 179% increase in the strongest slice are observed. The slice with the most intense increase is in the strongest slice and reveals the UHI effect.
城市热岛密度和发生与土地利用/土地覆被和地表温度变化密切相关。可以使用城市热区方差指数定量描述 UHI 的影响。本研究旨在利用 UTFVI 指数评估萨姆松市的 UHI 效应。使用来自 2000 年 ETM + 和 2020 年 OLI/TIRS Landsat 图像的 LST 数据来分析 UHI。结果表明，在 20 年内，萨姆松的沿海带的 UHI 效应增加。从创建的 UTFVI 地图进行的实地分析表明，在 20 年内，无切片减少 84%，弱切片增加 104%，中切片减少 10%，强切片减少 15%，更强切片增加 8%，最强切片增加 179%。增加最强烈的切片是最强切片，显示了 UHI 效应。
