混合型空氣品質模式在PM2.5源解析上之設計與應用

目前空氣污染的問題日益嚴重，這對環境以及人體的健康都造成了相當程度的影響，因此空氣品質的管控就顯得格外重要。而空氣污染源解析的技術在現今的空氣品質管控策略上是極為重要的課題，這部分也非常需要空氣品質模式的協助。目前有許多不同類型的空氣品質模式，但各個空氣品質模式之間依舊存在些許限制。因此本研究將整合不同特性的空氣品質模式，包含擴散模式AERMOD、軌跡模式HYPSLIT及網格模式CMAQ等，並以WRF氣象模式提供氣象初始場，建立出一套混合型的空氣品質模式方法。利用各個模式的優點來進行整合，提供更為有效的解析，包含原生性污染物、衍生性污染物及環境來源等資訊。並挑選了四個PM2.5高污染的案例日作為應用，探討台中火力發電廠以及台中交通移動源，對於台中地區PM2.5的影響程度。以及評析此混合型模式在使用上的情況，根據Hybrid模式模擬的結果顯示，台中火力發電廠在四個案例日期間，對於台中地區PM2.5的濃度影響佔0.1%~6.2%，其中衍生性的部分平均為2.84%，至於交通移動源對於台中地區PM2.5濃度的影響佔5%~21.6%，而原生性與衍生性平均分別佔7.5%及6.9%。

Increasingly serious air pollution greatly affects the environment and human health. Therefore, air quality control is particularly important. The technology of the source apportionment of air pollution is a very important issue. The work is also critically in need of the help from air quality models. Nowadays there are many different air quality models to help us find the source of the air pollution. However, the existing models have minor problems and each has its own limitations. Therefore this study will integrate different ways of air quality models. Include diffusion model (AERMOD), trajectory model (Hysplit) and grid model (CMAQ). Use WRF model to provide the meteorological initial fields. And through the avdantage of these models, this study builds a hybrid air quality model. Provide more effective analysis, including primary pollutants, secondary pollutants and other information of environment. This study selected four high PM2.5 pollution case days as the application. Discuss the influence of Taichung thermal power plant and Taichung traffic mobile source to the PM2.5 in Taichung area and evaluate the hybrid model. The results indicate that Taichung thermal power plants contribute 0.1%~6.2% of which the secoundary part is 2.84% to the PM2.5 concentration in Taichung area during the four case days. The contribution of traffic mobile source is 5%~21.6% to the PM2.5 in Taichung area. The primary and secondary part separately is 7.5% and 6.9%.
