摘要

摘要: 为了研究洛阳城市发展与城市热岛之间的关系，以近20年城区地表温度为研究对象，以陆地卫星（Landsat）卫星遥感数据作为数据源，通过温度反演方法研究4个时期地表温度，在Arcgis、ENVI5.3、Origin2018软件中加以分析，得到热岛效应空间分布和时空变化特征、地表温度和土地利用类型的关系，结果表明：自2001年到2019年老市中心（西工区）地表温度增温15℃；新市中心（洛龙区）地表温度增温11℃；不同用地分类中，水域的表面温度最低，且随着热岛增加，水域的冷岛效应略有增加，2001年洛河表面温度26℃，冷岛强度12℃，2019年洛河表面温度34℃，冷岛强度14℃。

Abstract: In order to study the relations between the urban development of Luoyang and the urban heat island, the surface temperatures of the urban area in the past two decades were taken as the research object. Landsat satellite remote sensing data was used as the data source, and the temperature inversion method was used to study the surface temperatures at four different periods. The analysis was conducted by using ArcGIS, ENVI 5.3, and Origin 2018 software. The spatial distribution and spatiotemporal variation characteristics of the heat island effect, as well as the relations between surface temperature and land use type, were obtained. The results indicated that from 2001 to 2019, the surface temperature of the old city center (Xigong District) increased by 15, and the surface ℃ temperature of the new city center (Luolong District) increased by 11 ℃. Among different land use classifications, ℃ the surface temperature of water bodies was the lowest, and with the increase of the heat island, the cold island effect of water bodies had slightly increased. The surface temperature of the Luo River was 26 in 2001, with a ℃ cold island intensity of 12, and in 2019, it was 34 ℃ with a cold island intensity of 14 ℃.
