From the past in 2003-2016 it was 14 years ago. Vientiane capital has changed the utilization of soil space and temperature has changed the usage land benefit and the temperature has changed dramatically because the city populations have increased continuously resulting in change the ecological and environment including the climate due to increase of building, surfaces and concrete that were absorbing the heat radiation and releasing heat to the atmosphere (Miller, 1997), in which the original area was transformed into a residential buildings, roads and expanded concrete area causing the density of the buildings to increase, but the soil cover decreased continuously it was caused the air near the surface changing and the temperature in the air rising due to accumulation heat in the cement surface from the heat energy of the sun. When saturated heat is released slow down than other materials causing the temperature to rise ( department of popular, 2009). increasing heat energy accumulation will cause the trend of temperature according to the proportion of the plants covered in the future will affect giving rise to heat phenomenon in the city (Urban Heat island).
