The underground thermal environment shows a complex structure that is affected by the topography, geological features, flow of underground water, rise in temperature from urbanization, the landcover composition and so on. In general, thermal temperature remains constant all year round at a certain depth from the ground surface. However, the results of actual measurement showed that the closer to the ground surface, the higher the annual temperature. This study, for the purpose of analyzing the causes of underground warming, calculated the underground temperature through numerical simulation. The study reviewed how changes in the landcover composition structure that forms the ground surface, the temperature rise from urbanization and flow of underground water affect underground temperature.
