摘　　要：针对景观格局变化对城市热舒适度的影响以及传统温湿度指标(temperature humidity index,THI)的局限,提出以反演地表温度和归一化湿度指数改进温湿度指标,并综合比较了不同阈值划分方法,建立了新的热舒适度分级体系。选取乌鲁木齐市为研究区,以2005年、2010年、2015年、2020年4年土地利用现状数据和夏季Landsat遥感影像为研究基础,通过计算景观格局指数,分析不同热舒适度分级下景观格局指数的变化,从景观组成以及结构特征2方面探究景观格局与城市热舒适度之间的关系。研究结果表明:景观格局的变化对乌鲁木齐市热舒适度有显著影响,水域、草地的密集分布与荒漠、建筑用地的稀疏分布对热舒适度具有显著改善作用。Focusing on the affection of changes in landscape patterns to urban thermal comfort and the limits of traditional Temperature and Humidity Index(THI),using surface temperature and the normalized humidity index to improve Temperature and Humidity Index(THI).Compared comprehensively with different threshold division methods,a new thermal comfort grading system was established.Land use data and summer Landsat photos from 2005,2010,2015 and 2020 are the research base and Urumqi City was chosen as the research area.The relationship between landscape pattern and urban thermal comfort was investigated from the viewpoints of landscape composition and structure by examining the changes in landscape pattern index under various levels of thermal comfort.The findings indicate that Urumqi City's thermal comfort is significantly impacted by changes in the landscape pattern.The dense distribution of water bodies and green spaces significantly improves thermal comfort while the sparse distribution of deserts and built-up areas has contrasting effect.
