Özet
The urban climate has been disrupted with increasing urbanisation and consumption concepts, revealing climatic properties that affect human comfort conditions as a result of climate change. Decreasing vegetation and evaporative surfaces in cities, and increasing structural surfaces, such as concrete and asphalt, alter the topography, ecological structure, and atmospheric characteristics of nature, creating a different ecology and atmosphere. In this study, the relationship between the land surface temperatures (LSTs) of green and impervious surfaces was examined in Nigde, Turkey. Various satellite images were used, and statistical and geographical analyses were conducted. The results revealed that the LST values changed with the changing ratio of impervious and green surfaces, and have increased in Nigde over the past three decades even though the amount of green surfaces have increased. Furthermore, the LSTs of the impervious surfaces are 5-10 degrees C higher than that of the green surfaces. A correlation analysis showed that there was a significant difference in the LST values between green and impervious surfaces. Impervious surfaces contribute to the formation of the urban heat islands (UHIs), and green surfaces provide a cooling effect. Thus, increasing the amount of green surfaces in cities is crucial to improve urban life quality.
