济南市城市热岛遥感反演

随着城市建设的高速发展,热岛效应越来越被人们所重视。本文采用2002年的Landsat ETM 遥感影像,阐述了地表温度反演的原理和计算方法;用ERDAS IMAGINE软件构建的模型反演济南地表温度得到地表温度图;分别从较低温区域、中温区、较高温区、特高温区、热核区,研究了济南市热岛效应的空间分布特征及其成因,并提出相应的措施。

Study on heat island inversion of Jinan city based on remote sensing

Along with urban construction's rapid development,city heat island effect becomes day by day prominent.In this paper,based on the remote sensing image of 2002,the author calculates the surface temperature inversion principle and computational method using ERDAS IMAGINE software construction model to inverse surface temperature so as to get surface temperature chart.And from low temperature region,warm area,high temperature area,special high temperature area,heat core area,the paper studies the city heat island effect of Jinan's spatial distribution characteristics and causes,and finally proposes the corresponding measures.
