卫星遥感对邢台市2024年的热岛效应分析
Analysis of the Heat Island Effect in Xingtai City by Satellite Remote Sensing in 2024

利用FY-3D气象卫星的遥感监测数据，对邢台市2024年度夏季热岛效应进行了分析，结果显示：2024年夏季邢台市全市平均气温28.1℃，较常年同期偏高1.8℃，为显著偏高年份。其中6月、8月为显著偏高年份，7月为正常年份。邢台市强热岛区域主要集中在城镇化程度较高的地区以及钢厂等热源工厂集中地区，农业种植区域、山区以及植被覆盖茂密区域大多呈弱热岛或无热岛现象。陆表高温与下垫面关系密切，以不透水层为主的城区陆表温度较高。从空间分布上看，夏季发生热岛效应面积最大并且较强热岛级别以上的区域主要分布在市区，其次是城镇化程度相对较高的区域。从热岛强度等级分布来看，邢台市以无热岛区为主，主要分布在郊区耕地，强冷岛和较强冷岛主要分布在西部山区等植被覆盖比较茂密区域。强热岛区和较强热岛区面积较小，主要分布于人口密集的城区。
Using the remote sensing monitoring data of FY-3D meteorological satellite, the heat island effect of Xingtai City in summer 2024 was carried out. The results show that the average temperature of Xingtai City in summer 2024 is 28.1？C, which is 1.8？C higher than the same period of normal years, which is a significantly higher year. Among them, June and August are significantly high years, and July is a normal year. The strong heat island area in Xingtai City is mainly concentrated in areas with a high degree of urbanization and areas where heat source factories such as steel mills are concentrated. Agricultural planting areas, mountainous areas, and areas with dense vegetation cover mostly show weak or no heat island phenomenon. The land surface temperature is closely related to the underlying surface, and the land surface temperature is higher in the urban area dominated by the impermeable layer. From the perspective of spatial distribution, the areas with the largest heat island effect in summer and above the strong heat island level are mainly distributed in urban areas, followed by areas with a relatively high degree of urbanization. According to the distribution of heat island intensity grade, the non-heat island area is the main area, mainly distributed in the suburban cultivated land, and the strong cold island and strong cold island are mainly distributed in the western mountainous area and other vegetation coverage areas. The area of strong heat island and stronger heat island is small, mainly distributed in densely populated urban areas.
