도시거주성 증진을 위한 미세먼지(PM10) 분포 추이에 관한 연구 :대구광역시를 중심으로

The purpose of the study is to analyze the relationship between air pollution(PM10) and land used patterns during recent 10 years. Study area has covered all area in Daegu and unit of spatial analysis was administrative dong. This study used spatial interpolation method including local trend surface model, IDW(Inverse Distance Weighted). Top 15 dong of pm10 values in Daegu 139 administrative dong was Jukjeon-dong, Gosan 3 dong, Bisan 1·5·7 dong, Jisan 1·2 dong, Pyeongni 3·4·5·6 dong, Nowon dong, Naedang 4 dong, Sangjungi dong, Ansim 1 dong. It was Daegu dyeing industrial and West daegu industrial complex association around the area. Especially in Bisan 1·5 dong, Pyeongni3·5 dong of high contamination density region, population density is relatively high, it is possible that many people at risk of PM10 high concentration. Based on overlay analysis techniques with pm10 values and land used patterns, residential, commercial, industrial area belonged to areas with high air pollution(PM10) concentration. On the other hand, in the case of the region is not a city of the region, it was less relatively air pollution concentration. Therefore, the study was possible to obtain a reslut of increased levels of PM10 concentration by process of development caused when the city has evolved or use characteristics.
