| 摘 要： | 随着城市化进程的加速,城市热岛效应越来越受到人们重视.喀斯特地区以其独特的地貌特征,表现出不同的热岛形成和分布情况.本文采用覆盖贵阳市的2001年ETM+和2007年TM遥感影像,进行亮度温度反演,分析热岛分布和形成原因.研究表明:除了常规热岛外,在贵阳市还广泛存在着与喀斯特的分布和石漠化的形成有着密切联系的异常热岛区... |

| Abstract: | Along with the rapid development of urbanization,the urban heat island effect(UHI) has attracted great attention.Because of especial surface features,the karst area has shown different heat island effect forms and distributions.By using the Landsat ETM+ and TM images which were obtained in 2001 and 2007,the surface brightness temperature was computed and the urban heat island distribution and form in Guiyang City were analyzed.The result showed that besides the normal UHI,there is commonly existing especial... |
