101年6月世界衛生組織（WHO）的國際癌症研究署（IARC）將柴油引擎排放的廢氣，公告為第一類確定致癌物質，等同砒霜及石棉，柴油車廢氣對環境與人體健康有重大影響，為維護空氣品質，對高污染柴油車加嚴管制有其必要性。 本研究探討阿里山地區高山柴油車排煙污染管制措施，結合問卷、半結構式訪談進行資料蒐集，藉由柴油大客車排煙檢測結果，作為污染改善的佐證效益。本研究透過問卷及訪談探討得知遊客肯定柴油車排煙污染管制政策，希望能持續推動，在實地檢測結果也顯示管制成效。 結論建議，政府機關應加強「阿里山空氣品質淨區」全面性的宣導，強化到訪阿里山風景區遊客及居民環境保護意識，將管制高污染車輛的作法，推廣成為到訪阿里山遊客寶貴的旅遊經驗，讓烏賊車絕跡於各風景區。 International Agency for Research on Cancer (IARC) announced that the exhaust emission of diesel engine is Group 1 carcinogens in 2012, which is equal to arsenic and asbestos, hence the exhaust emission of diesel engine made a great impact on environment and health. It is necessary to imposed strict controls on diesel vehicle with high pollution in order to protect the air quality. The present study examines the control measures of diesel vehicle’s exhaust emissions in Alishan National Scenic Area, it is doing a data analysis which combined with questionnaire and semi-unstructured interview; in turn utilized the examination report of diesel vehicle’s exhaust emissions to be a paradigm that air pollution had been improved. From the results, the study got an information about there are lots of travelers endorsed the control measures of diesel vehicle’s exhaust emissions, and hoped to persist in promoting. The study suggested that the government should enhances the announcement of clear air quality in Alishan National Scenic Area, and reinforces people’s environmental consciousness, and works hard to promote the policy to everywhere, so that ease the risks of air pollutions.
