Abstract | The urban temperatures are increasing globally, in some urban places the urban heat is restoring because of high dense concrete constructions development in both horizontal and vertical directions these zones are called Urban Heat Island(UHI).Generally, the temperature variation between the rural and urban should be about 5.60C.In this research we considered the mixed classes for land use and land cover analysis specially to study more on the built up area in the Bangkok city. In case of Bangkok city based on the grid base analysis the grids which are having the highest percentage of built up, located in the center of the city and industrial areas is restoring heat. Bangkok city UHI value in November 3.130c, in December 3.370c, 2.240c, 3.470c and 3.560c, in January 3.370c, 2.830c, 2.830c and 3.390c and in February 3.220c, 4.180c, 2.740c and 3.80c.The average UHI temperature for winter season of 2015 is 3.240c with standard deviation 0.505.Since the standard deviation value is very less this shows that UHI data set is very close to the mean UHI which signifies the consistency of UHI temperature in the winter season for 2015.The highest difference of temperature noted in the month of the February. From the results we can say that the grids that are consider as UHI are having more than 83.86%covered by the built up so they are repeatedly falling in critical and along the boundary of the Bangkok city even though the grid is having the more built up it is not considered as the UHI because there is heat exchange between the adjacent land cover respectively, which moderated the temperature If the count is 13 these zones are located in core city zone with high percentage of built up. If we consider 83.86% as mark for UHI about 18grids are under UHI zones which mean 72sq.km of total area under the UHI. |
