| Summary: | 碩士 === 國立屏東科技大學 === 環境工程與科學系 === 90 === Environmental Protection Administration (EPA), Government of the Republic of China has initiated their second stage of air pollution emission fee collection since from July 1, 1998. The fee was originally collected by the amount of fuel used through fuel charge, but now it has been changed to the amount of actual emission. In order to reach the goal of reducing air pollution, Kaohusing City government has drawn up and promotioned many kinds of air pollution protecting plans in the past few years. Therefore, the air pollution emission fee could be used to improve the air quality in Kaohsiung. In order to discuss the relationship between the air pollution emission fee of stationary pollution sources (factories) and the air quality ( SO2, NOx ) in Kaohsiung City, we used the data from EPA air quality monitoring stations in this study. The data was collected from seven monitoring stations which were located in San-Min, Xiao-gang, Zuo-ying, Qian-jin, Qian-zhen, Nan-Tze, and Fu-xing separately to discuss the relationship between the amount of collecting fee and the air quality. The results showed found that the concentrations of sulfur dioxide in each monitoring station in Kaohsiung was gradually increased from north to south. One of the reasons might be that the total amount of sulfur dioxide emission in Xiao-gang district located in the southern part of Kaohusing City is the highest. Therefore, the concentration of sulfur dioxide in Xiao-gang district affected the air quality of neighboring district. The weather factors also influenced the concentration of sulfur dioxide that was gradually increased from north to south. Besides, in both general monitoring stations and traffic monitoring stations, moving pollution sources only contributed little influence on the concentration of sulfur dioxide in monitoring stations. As to the influence of nitrogen oxides, it depends on the proportion of stationary pollution sources and moving pollution sources. Although both the actual amount of pollution emission fee collected and the air pollution have decreased in Kaohsiung these year, there is no evident to show the trend of correlation between these two. Future, works will focus on the control of total amount emission. Periodical evaluations of each air quality monitoring station and the overall air pollution control policy are recommendated.
