Abstract

The need for built-up areas continues to increase, along with the increasing population in the city of Surakarta and its surrounding. This condition affects the land surface temperature which then leads to the change in climatic conditions. The availability of land for settlement and surface temperature will affect the comfort level of living in a city. For this reason, this study aims to map the distribution of built-up area and the surface temperature of Surakarta city and discusses the relationship between these two aspects spatially and temporally. The data used are Landsat imageries recorded in 2000, 2013, and 2019. The built-up area was identified using Normalized Difference Built-Up Index (NDBI), while the temperature data was obtained through thermal band processing using Land Surface Temperature (LST) method. The results showed that during the period of the study, the built-up area and the surface temperature in Surakarta and its surroundings increased, especially in the eastern and southern parts of Surakarta. The results also showed that there is a positive correlation between the built-up index and its surface temperature.
基于Landsat影像的泗水市建成区面积和地表温度时空分析
随着苏拉卡塔市及其周边地区人口的增加,对建成区的需求继续增加。这种情况会影响地表温度,进而导致气候条件的变化。定居用地的可用性和地表温度将影响城市生活的舒适度。因此,本研究旨在绘制苏拉卡塔市建成区面积和地表温度的分布图,并从空间和时间上讨论这两个方面之间的关系。使用的数据是2000年、2013年和2019年记录的陆地卫星图像。使用归一化差异累积指数(NDBI)识别建成区,而使用地表温度(LST)方法通过热带处理获得温度数据。结果表明,在研究期间,苏拉卡塔及其周边地区的建成区面积和地表温度都有所增加,特别是苏拉卡塔的东部和南部地区。结果还表明,堆积指数与其表面温度呈正相关。
