摘要
随着赤峰市城市化进程的不断加快,热岛效应凸显,其所产生的问题也逐渐暴露。使用Landsat遥感影像作为数据源,对2014—2021年的赤峰市城区地表温度变化特征进行分析。结果表明:截至2021年,赤峰市城区地表温度逐渐增高,在空间分布上,高温区和次高温区由城市边缘逐渐向内发展,中温区、次中温区范围大幅增加,低温地区的范围逐渐减少。因此了解地表温度变化特征对合理规划赤峰市城市建设,促进可持续发展等具有重要意义。
With the accelerating urbanization process of Chifeng city,the heat island effect was prominented,and its problems are gradually exposed.Landsat remote sensing images were used as data sources to analyze the characteristics of land surface temperature change in chifeng city from 2014 to 2021.The results show that by 2021,the surface temperature in the urban area of Chifeng is gradually increasing.In terms of spatial distribution,the high temperature area and the sub-high temperature area were gradually developing inward from the urban edge,the range of the moderate temperature area and the sub-middle temperature area was greatly increased,and the range of the low temperature area is gradually decreasing.Understanding the characteristics of land surface temperature change is of great significance for planning the urban construction and promoting the sustainable development of Chifeng city.
