This paper focuses on land use and land cover (LULC) expansion and local climate zone (LCZ) changes in relation to warming in the future, the study concentrates on three major parts. First, this research analyzes LULC and LCZ changes from 1991 to 2016 using Landsat satellite images data. This reveals the history of urban expansion over the study period, urban growth rate and urban land demand projection in the target year (2026). Second, the study determines LULC and LCZ changes in the future by using spatial logistic regression model. Third, the examination of urban expansion in relation to warming in the future was conducted. The result shows that the built-up area has more development and expansion to the northern, southern and western parts of Bangkok. The built-up surface temperature climbed and continued to increase between 1991 and 2016. The trend of temperature differences between the built-up areas and other areas, significantly widened in 2026. Most of green area on the western part of Bangkok was replaced by compact mid-rise, compact low-rise, and open low-rise building. The study means that the western part of the city will be warmer approximately 1 to 2 °C in the future.

与地表温度有关的未来城市扩展和当地气候区变化:以泰国曼谷市政府为例

本文着眼于未来土地利用和土地覆盖(LULC)的扩展以及当地气候带(LCZ)与变暖的关系,研究主要集中在三个主要部分。首先,这项研究使用Landsat卫星图像数据分析了1991年至2016年期间LULC和LCZ的变化。这揭示了目标时期(2026年)研究期内城市扩张的历史,城市增长率和城市土地需求预测。其次,该研究通过使用空间逻辑回归模型确定未来的LULC和LCZ变化。第三,研究了与未来变暖有关的城市扩张。结果表明,建成区向曼谷北部,南部和西部地区发展和扩展。在1991年至2016年期间,建筑表面温度上升并持续上升。建成区与其他区域之间的温差趋势在2026年显着扩大。曼谷西部的大部分绿色区域被紧凑的中层楼房,紧凑型低层楼房和开放式低层楼房所取代。该研究表明,该城市的西部地区将来可能会变暖大约1至2°C。
