Abstract

The Surface Urban Heat Island (SUHI) effect refers to the difference in Land Surface Temperature (LST) between an urban area and its surrounding non-urban area. LST can provide detailed information on the variations in different types of land cover. This study, therefore, analyzes the behavior of LST and SUHIs in fourteen cities in the El Bajío Industrial Corridor, Mexico, using Landsat satellite images from 2020, with QGIS software. It utilizes thermal profiles to identify the land uses that intensify LST, which are essentially those that are anthropologically altered. The results show that the increases in LST and SUHI are more pronounced in cities with greater urban conglomeration, as well as those where there are few green areas and a sizeable industrial or mixed area, with few or no bodies of water. In addition, the increase in temperature in the SUHI is due to certain crops such as vegetables, red fruits, and basic grains such as corn, wheat, and sorghum that use fallow as part of agricultural practices, located around urban areas, which minimizes natural areas with arboreal vegetation.

2020年墨西哥El Bajío工业走廊城市地表热岛和热剖面数字图像分析

地表城市热岛效应是指城市区域与其周边非城市区域之间的地表温度差异。地表温度可以提供不同类型土地覆盖变化的详细信息。因此，本研究利用2020年以来的Landsat卫星图像，利用QGIS软件，分析了墨西哥El Bajío工业走廊14个城市的地表温度和SUHIs的行为。它利用热剖面来确定加剧地表温度的土地利用，这基本上是那些被人类改变的土地利用。结果表明，在城市群较大的城市，以及绿化带较少、工业或混合区较大、水体较少或没有水体的城市，地表温度和SUHI的增加更为明显。此外，SUHI地区的温度升高是由于某些作物，如蔬菜、红色水果，以及玉米、小麦和高粱等基本谷物，作为农业实践的一部分，位于城市地区周围，这使拥有树木植被的自然区域最小化。
