Urban Heat Island Study Based on Landsat Remote Sensing Images: A Case Study of Hangzhou

Urban is the center of the region society, economy, politics and culture. And urban is a symbol of human civilization and development. Urbanization is a common trend in many countries. In developing countries, this situation is particularly evident. With rapid urbanization, there are lots of environment problems. Among these environmental problems, the urban heat island effect is the most important. UHI has deep impacts on material cycles and energy transfers within urban ecosystems and has become an important issue in urban climate and environmental research. Hangzhou is an important city in the urban circle of the Yangtze River delta as the capital of Zhejiang Province in China. And nowadays, Hangzhou is in a period of rapid development. With the development of urban, the environmental problems become more and more important, especially the urban heat island effect. This paper, based on the Multi-time-phase TM /ETM+ Remote Sensing images, takes Hangzhou as an example to contrast four time inversions results and study the evolution rule and the characteristic of the heat island effect with Single-Channel Algorithm. Through this study, we can find the evolution law of urban heat island in Hangzhou. And then for the future development of cities and solutions to the urban heat island effects, it can provide a more effective way of train of thought and methods Index Terms— GIS; Remote Sensing; Urban Heat Island; Land Surface Temperature; Single-Channel Algorithm
