Yangon is the old capital city and the most important commercial city of Myanmar. The urban area of Yangon city has been rising rapidly and great changes have taken place in the past 20 years, especially after 2000. The population and urban size of Yangon have grown tremendously between 2000 and 2019. In 2019, the population of Yangon city is approximately 4477638 and the population density is 12308 per square kilometre. The disadvantages of having a large population and urbanization are many facts. Deforestation, land surface temperature and urban heat island (UHI) have resulted from them. Heatrelated illness is the consequence of surface and air temperature rising. Since the past ten years ago, heat-related illnesses were many occurred in Yangon city. The study area has been selected by two main facts (1) population and (2) the rate of urbanization. This study aims to investigate the reaction among the deforestation, land surface temperature (LST) and urban heat island (UHI) in Yangon city. The main data was landsat7 ETM+ of 17 February 2003 and landsat8 of 21 February 2019 satellite images which were cloud-free data. Many spatial statistical equations and methods were applied to this research process. The research shows that the minimum land surface temperature (LST) is rising from 25.1046 °C to 26.2854 °C and the maximum is 42.1150 °C to 43.7832 °C from 2003 to 2019. The vegetation coverage (NDVI) has decreased and the urbanization area (NDBI) has increased. In the study area, the urban heat island (UHI) intensity was correlated with land surface temperature (LST), vegetation coverage and urbanization area. |
