摘要
利用2002年7月11日的ETM+数据,经辐射定标、6S大气校正、比辐射率的估算,用单窗算法对合肥市进行了地表温度的反演,并进行土地分类。在此基础上对合肥市进行了热岛研究,分析了地表温度和地表特征参数的相关性,同时探讨了城市河流对城市热岛的影响。结果表明,植被指数对地温的解释程度最好,并表明河流水体对城市热岛有一定的减缓效应。
Using Landsat ETM ＋ data of Hefei City in July 11th,2002,after the radiometric calibration,atmospheric and emissive correction,inversion of land surface temperature according to mono-window-algorithm,the land classification was carried out.The heat island effect of Hefei City was studied,and the relationship between temperature and land surface parameter was analyzed,and the influence of the urban heat island of city river was discussed.Results showed that the vegetation index to explain the extent of temperature was the best,and the water body had some alleviation effects on urban heat environment.
