| 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。

| Abstract: | 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. |
