Dynamical Monitoring and Evaluation Methods to Urban Heat Island Effects Based on RSGIS

摘要

At present, research about Urban Heat Island Effects (UHI) is a hot issue in urban climate and ecological environment. Because remote sensing technology has many advantages, it becomes an important means of UHI research. How to use multi-temporal thermal infrared remote sensing data and dynamically monitor and evaluate UHI is a very interesting research topic. This article took Luzhou City in Sichuan Province, China as an example and explored methods to monitoring and evaluating UHI based on Landsat-5 TM data, which obtained on September 15, 1988, and Landsat-7 ETM+ data which obtained on August 29, 2002.Technical methods and research route established by this article can provide references for other similar research, and have application and popularizing value.
