초록
본(本) 연구(硏究)에서는 울산지역(蔚山地域)을 대상(對象)으로 CDMQC 모델을 이용(利用)하여 대기질(大氣質)을 예측(豫測)하였으며 아울러 동일대상지역(同一對象地域)에서 실측(實測)을 시행(施行)하므로써 전산(電算)모델을 이용(利用)한 예측치(豫測値)와 실측치간(實測値間)의 비교검토(比較檢討)를 실시하였다. 모델링결과(結果) 가장 오염(汚染)이 심한 지역(地域)은 부곡동(夫谷洞)과 여천동지역(呂川洞地域)으로 연평균(年平均)
This study involves 1) air quality disperson predictions and 2) a comparison of the predicted data with the actually measured ones in terms of annual sulfur dioxide concentration in the Ulsan Industial Complex. The prediction was made by utilizing the CDMQC air quality simulation computer model. The higher concentrations were observed at the Bugok Dong (Sampling Site) and the Yeochun Dong Sampling Site with the values of 44 and 46 ppb, respectively whereas the predicted values for both sites were 52 and 47 ppb, respectively. A statistical examination has revealed that the level of confidence was 90.02% from the Chi-squared test and the corelation coefficient was 0.827. It thus demonstrates that the model used for the study appears to be applicable to yield reliable predictions in terms of annual sulfur dioxide concentrations in the study area.
