地表温度（LST）作为城市健康和可持续发展的一个指标，正受到越来越多的关注。随着城市化和工业化进程的加快，城市热岛现象在许多城市普遍存在，导致能源过度消耗，气候和环境恶化。优化土地利用/覆盖（LUC）分布可以减少城市热岛现象。因此，监测土地利用变化并分析其对土地利用变化的影响对城市健康发展至关重要。在这项研究中，试图研究LST和LUC的变化，日本札幌。利用Landsat数据，我们试图分析1985年至2015年每个LUC类别的LST。结果表明：（1）LUC类型和空间分布对地表温度有很大影响;（2）扩张性开发是近30年来影响城市热岛现象的最重要因素;（3）绿色空间和水域有助于城市降温。这项研究揭示了LUC分布和LST之间的密切关系，为未来的LUC模拟开辟了研究途径。我们的分析不仅有助于城市健康和可持续发展，还为提升城市竞争力提供了重要见解。
Land surface temperature (LST) is receiving increasing attention as a measure of urban health and sustainable development. With rapid urbanization and industrialization, the urban heat island phenomenon, which causes excessive energy consumption and climatic and environmental deterioration, has become prevalent in many cities. It is well known that optimizing land use/cover (LUC) distribution can reduce the urban heat island phenomenon. Therefore, monitoring LUC changes and analyzing their effects on LST is crucial for healthy urban development. In this study, an attempt is made to examine LST and LUC changes in Sapporo, Japan. Using Landsat data, we attempted to analyze the LST in each LUC category from 1985 to 2015. The results show that: (1) LUC types and spatial distribution have great influences on LST, (2) expanding development has been the most significant factor affecting urban heat island phenomenon over the past 30 years, and (3) green space and water areas have helped cool the city. This study revealed a strong relationship between LUC distribution and LST, opening research avenues for future LUC simulation. Our analysis not only contributes to urban health and sustainable development but also provides significant insights into the promotion of city competence.
