基于Landsat ETM^+图像的南昌市地表温度反演与分析

Calibration and Analysis of the Surface Temperature in Nanchang City Using Landsat ETM^+ Data

在遥感图像处理系统的支持下,利用2003年2月4日的Landsat ETM+第六波段数据,经过大气和比辐射率校正后,反演南昌市主城区的地面温度,得出南昌市主城区冬季地面温度场的分布规律。结合植被和水体等土地覆盖信息,进一步研究植被盖度、水体面积比例与地面温度的相互关系。

Under the support of RS software and using Landsat ETM^＋ band 6 data on Feb. 4, 2003, this paper conducts a surface temperature caliberation in Nanchang emmisive correction. The land temperatural spatial distribution ships between temperature and vegetation coverage, water ratio City, Jiangxi Province after atmospheric and characteristics are clarified and the relation- are identified as well in this paper.
