| Abstract |
To relieve urban high temperature phenomenon like heat island, analyzing urban structure is needed. In that case utilizing GIS which manages numerous information can be an effective access. Therefore this study aims at constructing EGIS DB of Haeundae, a coastal area, performing statistical analysis for understanding urban structure and ultimately accomplishing numerical simulation. The accomplished results of this study are as follows. 1)Building Information Database is constructed as integrating digital maps and building register file into a GIS Database. 2)EGIS DB is constructed as mesh data with environmental information data and the preceding building information database. 3)EGIS DB is converted into statistical data supporting to accomplish statistical analysis and calculate urban structure factors' figures according to the Frequency Analysis. 4) On the base of 18 urban planning items of study area, 6 component is pulled out and whole study area is grouped as 8 types according to the Principal Component Analysis. 5) To evaluate thermal environment of 8-type group, Urban Climate simulation of a Summer hottest day is carried out by UCSS (Urban Climate Simulation System) Box Model and the result is analyzed on the side of air temperature and heat budget. |
