本二年計畫主要目的在篩選適合石化工業區種植之高淨污及快長樹種，以供日後石化工業區綠化推薦樹種之參考依據。第二年係針對煉油及石化工業區中油廠區進行五項工作，包括(1)相關高淨污及快長樹種資料之蒐集， (2) 現場調查3個以上之現有石化工業區高淨污及快長之樹種，(3) 實測與篩選高淨污及快長樹種，研究測定之污染物對象為（碳氫化物代表物甲苯、氟化氫、臭氧）等三項及鹽沫一項。(4) 綜合評估選列高淨污及快長之樹種，(5) 彙編「我國石化工業區適合高淨污及快長樹種」手冊。目前已增加相關文獻，已到四座煉油及石化工業中游廠區調查常見耐污樹種，計有榕樹、茄苳、樟樹、小葉欖仁、水黃皮、欖仁、印度紫檀等約23種。已進行此些樹種對甲苯、氟化氫、臭氧之淨污能力之實測與篩選，以選出高淨污及快長之樹種。有關彙編「我國石化工業區適合高淨污及快長樹種」手冊項目，已收集相關資料及圖片，並已完成初稿。本計畫有關污染測定技術皆已成熟，故預期皆可達成預定之目標，並彙編「我國石化工業區適合高淨污及快長樹種」手冊。本計畫將可在計畫完成後，精確評估適合石化工業區種植之高淨污及快長樹種，以供環保及工業區單位未來植樹造林之參考，亦可供未來各環保單位設置空品淨化區選擇樹種之參考。此些研究所得，皆具實際參考及應用之價值，故擬於計畫完成後，適當予以發表於研討會或學術雜誌中，並提供環保署上網公佈，供各界之應用及參採，以降低石化工業區之空氣污染，提升周遭及國家之環境品質。其研究測定之污染物對象為O3、VOC之C7H8、HF三項及鹽沫一項。本年度之計畫已經由繞廠調查，對台灣地區三座石化工業區現有常見樹種，選取目前生長具優勢之樹種，且屬於台灣地區常見之高淨污或快長樹種，分成內陸適合及濱海適合兩類，選取內陸適合樹種11 種，而選取濱海適合樹種12 種，合計共23 種。此23 種列為本計畫所有測試之目標，包括耐鹽能力及對重要污染氣體之吸收淨污能力等。至2011年12月，已完成23種樹種之耐鹽能力及三種污染氣體淨污能力測試，結果發現黃連木、白水木、檉柳、欖仁、榕樹等具有較高之臭氧吸收能力；水黃皮、海棗、木麻黃、黃連木、茄冬等具有較高之甲苯（碳氫化物代表物）吸收能力；小葉欖仁、榕樹、白水木、檉柳、台灣櫸具有較高之氟化氫吸收能力；而大葉山欖、小葉南洋杉、海棗、檉柳、木麻黃、春不老、白水木、水黃皮及榕樹等具有較高之鹽沫耐受度。經整合評估後，適合內陸石化工業區之高淨污樹種建議推薦台灣櫸、黃連木、檸檬桉、小葉欖仁及苦楝等；而適合濱海石化工業區之高淨污樹種則建議推薦木麻黃、小葉南洋杉及檉柳等。

The purpose of this two-year project is to screen and evaluate the fast-growing and high-pollutant-uptake trees for petrochemical industrial parks in Taiwan. The first-year study is focusing on industrial parks with naphtha-cracking factories. There are four major tasks in this first-year project: (1) To review all the literatures related with fast-growing and high-pollutant-uptake trees in petrochemical industrial parks; (2) To investigate and identify all tree species growing well in at least three petrochemical industrial parks; (3) To measure the pollutant uptake rates of major tree species belonging to fast-growing and high-pollutant-uptake group with instruments; (4) Comprehensive evaluation and grading all the fast-growing and high-pollutant-uptake trees species tested in this study for future application in petrochemical industrial parks in Taiwan. The measurements of pollutant (including O3, C7H8, and HF) uptake rates by tree species were conducted in bag branch enclosure chamber. The tolerance of these tree species to salt spray were also tested for evaluating their performance in inland or coastal areas. After a series of field investigation around three petrochemical industrial parks in Taiwan, a total of 23 tree species were preliminarily selected and listed for detail measurements of pollutant uptake rates and salt spray tolerance. We have compared the O3 uptake rates of them and found that among them chinese pistachios, silvery Messerschmidia, juniper Tamarisk, Indian almond, and marabutan can do the better job. To C7H8, the higher uptake rates were found on poongaoil pongamia, date palm, iron wood, chinese pistachios, and red cedar. For HF uptake measurement, madagascar almond, marabutan, silvery messerschmidia, juniper tamarisk and Taiwan zelkova showed the higher uptake rates. Results also showed that Taiwan nato tree, Norfolk island pine, date palm, juniper Tamarisk, iron wood, seashore ardisia, silvery Messerschmidia, poongaoil pongamia, and marabutan were salt tolerant species.
