本研究主要利用化學質量平衡(CMB)受體模式分析高屏及中部空品區PM10 (氣動直徑小於10μm之懸浮微粒)的污染來源,並應用ISC擴散模式模擬實施PM10減量策略,造成PM10、SO2及NOx之濃度變化情形,結合此二個模式之模擬結果再進一步評估PM10減量策略對空氣品質的影響。評估結果顯示高屏地區90年管制對策可使高屏地區民國90年懸浮微粒PM10平均濃度從未管制時之95.9 μg/m3降低至89.6 μg/m3 (事件日發生比例則從18.5 %減少至14.1 %),95年管制對策則可使民國95年PM10平均濃度從未管制時之98.1 μg/m3降低至91.3 μg/m3 (事件日發生比例從未管制時之20.3 %減少至14.8 %)。因此,本研究所採用之高屏空品區管制對策對高屏空品區之空氣品質具有一定的改善效果,但要達到環保署所定之目標,仍需訂定更嚴格之管制對策。中部地區環保局擬定的管制對策效益評估方面,在90年管制對策實施後,推估其懸浮微粒PM10平均濃度可從管制前102.4 μg/m3降至80.9 μg/m3 (平均濃度為七個測站之平均),各測站PM10改善比例方面,屬於沿海測站之梧棲,都會區之彰化及崇倫測站的改善比例分別為22.7 %、22.5 % 及19.0 %,屬於內陸測站之南投、竹山、草屯及埔里測站之PM10的改善比例則分別為22.8 %、22.2 %、21.6 %及17.3 %。

In this study we analyzed the source apportionments of PM10 in the Kao-Ping and the Central Taiwan Air Basins by using a Chemical Mass Balance receptor model (CMB). An Industrial Source Complex dispersion model (ISC) was used to evaluate the impact of implementing the PM10 abatement strategies in these areas. The results indicated that the average PM10 concentration reduced from 95.6 μg/m3 to 89.6 μg/m3 in 2001 and from 98.1 μg/m3 to 91.3 μg/m3 in 2006 in the Kao-Ping area. These data showed the percentage of unhealthy air quality station-days (PSI>100) could reduce from 18.5 % to 14.1 % in 2001 and from 20.3 % to 14.8 % in 2006. In conclusion the control strategies used in this study could improve the air quality in the Kao-Ping area. However the control strategies still needed to be strengthened in order to achieve the goal of a better air quality required by Taiwan Environmental Protection Administration. Regarding the evaluation of air quality for the Central Taiwan, the control strategies proposed by the local Environmental Protection Bureau could reduce the average PM10 concentration from 102.4 μg/m3 to 80.9 μg/m3 in 2001. The percentage improvement of PM10 at the Wuchi coastal site, the urban Changhwa and Chunglun sites, the inland Nanton, Chushan, Tsaotun, and Puli sites were 22.7 %, 22.5 %, 19.0 %, 22.8 %, 22.2 %, 21.6 % and 17.3 %, respectively.
