基于遥感影像的合肥市热岛效应分析

Analysis of heat island effect in Hefei city based on remote sensing image

以合肥市为例,采用中高分辨率的地图Landsat TM/ETM及Landsat 8OLI/TIRS等数据,借助遥感技术,运用ENVI,ARCGIS等遥感操作系统软件,提取合肥市的地表温度分析数据,并通过制作和输出的城市专题温度图表等对其主要影响因素数据进行分析,得出合肥市热岛效应的地理特征及影响分布区,并提出减缓热岛效应的相关措施。

Taking Hefei as an example,using high-resolution map Landsat TM/ETM,Landsat 8OLI/TIRS and other data,with the help of remote sensing technology,operation ENVI,ARCGIS and other remote sensing operating system software,extract the surface temperature analysis data of Hefei City.The geographical characteristics and influence distribution areas of the heat island effect in Hefei are derived by analyzing the data of the main factors such as the urban thematic temperature chart produced and exported.The relevant measures to mitigate the heat island effect are also proposed.
