Data underlying the publication: Change Detection in a Rural Landscape: A case study of processes and main driving factors and its response to land surface temperature and heat island phenomenon in Farim, Iran

This study aims to investigate the alteration of land use land cover (LULC) change and its response to change in land surface temperature (LST) and heat island phenomena of a rural district of Farim in the north of Iran from 1990 to 2020 using multi-date Landsat data. The LULC result suggests that most land cover type changes are dedicated to bare land with a 24.83 km2 gain (+80.87%). The result demonstrates that the main changing factors of the bare land are population/precipitation and temperature/population. Additionally, the effect of LULC change on seasonal LST and urban heat island (UHI) is also analyzed in this study. The result witnessed a significant rise of LST in both the summer and winter seasons of about 12.87 °C and 14.2 °C, respectively. The urban thermal field variance index (UTFVI) shows the strongest zone in the central area and no UTFVI zone in the surrounding region.

本研究旨在利用多期陆地卫星（Landsat）数据，探究1990年至2020年间伊朗北部法里姆乡村地区的土地利用/土地覆被（Land Use Land Cover, LULC）变化及其对地表温度（Land Surface Temperature, LST）变化与热岛现象的响应。LULC分析结果显示，绝大多数土地覆被类型变化均集中于裸地，裸地新增面积达24.83 km²，增幅为80.87%。研究结果表明，裸地变化的主要驱动因素为人口/降水量与温度/人口比值。此外，本研究还分析了LULC变化对季节地表温度与城市热岛（Urban Heat Island, UHI）的影响。结果显示，夏季与冬季的地表温度均出现显著升高，分别约升高12.87 ℃与14.2 ℃。城市热场方差指数（Urban Thermal Field Variance Index, UTFVI）结果表明，热岛最强区域位于中部区域，周边区域无对应指数覆盖区。
