摘　　要：以2011年Landsat-5和2014年Landsat-8为数据源,利用RS和GIS建模反演东莞市地表温度,研究东莞市2011年和2014年热岛效应,结果表明:用Landsat-5、Landsat-8反演地表温度是可行的;东莞市热岛效应的分布与植被、水体及下垫面有重要关系;2011年东莞市热岛强度以强热岛为主,2014年以中热岛为主;2014年与2011年相比,热岛效应总体下降。Based on the 2011 Landsat-5 and 2014 Landsat-8 as the data source, the dynamic change of heat island effect distribution of Dongguan city in 2011 and 2014 was studied through RS and GIS inversion modeling retrieved the ground brightness temperature. The results showed that using land surface temperature Landsat-5 and Landsat-8 satellite data to retrieve the ground brightness temperature in Dongguan city is feasible; the distribution of heat island of Dongguan had relations of vegetation, water, and underlying surface. The heat island was given priority to with medium heat island in 2011 and the heat island was given priority to with strong heat island in 2014 in Dongguan. The heat island, compared with 2011, was decline in 2014.
