彰化空氣品質淨化區設置對空氣品質改善效益之研究
A study on the air quality improvement of establishment of clean air zones in Changhua County
摘要
本研究討論在2022年1～12月，於彰化縣鹿港鎮環保運動公園（以下簡稱「鹿港運動公園」）和彰化縣埤頭鄉埤頭段656號綠化地（以下簡稱「656號綠化地」）兩個空氣品質淨化區（以下簡稱「空品淨化區」）內，各設置一組微型感測器以取得區內空氣相關數據，同時在空品淨化區外亦設置感測器，以分析比較空品淨化區內外的空氣品質。本研究將探測氣溫、二氧化碳濃度與空氣懸浮微粒（主要針對PM_(2.5)與PM_(10)）濃度之變化，並判讀各項數據以了解空品淨化區之空氣品質改善狀況。但影響空氣品質的因子諸多，例如氣溫高時，大氣混合層高度較高，空氣汙染物較能擴散，空氣品質較佳。但經統計分析，氣溫與二氧化碳及懸浮微粒之變化趨勢呈不顯著關係，顯示影響空氣品質得因素很複雜，氣溫並非主要因子。最後由成果可知，無論鹿港運動公園或656號綠化地，空品淨化區內之空氣品質幾乎都比區外略好，顯示空品淨化區對改善空氣品質仍有一定效果。

Throughout the year 2022 (from January to December), this research collected air quality data by setting up micro sensors inside and outside two clean air zones: the environmental sports park in Lukang, Changhua (hereinafter referred to as "Lukang Sports Park") and the green land at No. 656, Pitou Section, Pitou Town, Changhua (hereinafter referred to as "No. 656 green land"). This research aims to evaluate the improvement of air quality in the aforementioned clean air zones by analyzing and comparing the changes in temperature and the concentration of carbon dioxide and aerosols (mainly PM 2.5 and PM 10). However, there are many factors that affect air quality. For example, the higher the temperature, the higher the atmospheric mixing layer. As a result, air pollutants diffuse faster, and the air quality gets better. However, according to statistical analysis, there is no significant correlation between the temperature and the changes of carbon dioxide and aerosol concentration, which shows that the factors affecting air quality are complicated and temperature isn't the main factor. Lastly, as can be seen from the charts, regardless of Lukang Sports Park or No. 656 green land, the air quality in the clean air zones is slightly better than that outside. This indicates that clean air zones still have a certain effect on improving air quality.
