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。第一年係針對輕油裂解石化工業區進行四項工作，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，(4) 綜合評估選列高淨污及快長之樹種。其中包括以儀器實測常見石化工業區樹種淨化污染之能力，並篩選適合於濱海石化工業區之淨污及快長樹種。其研究測定之污染物對象為SO2、C2H4、NOx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2010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，結果發現小葉南洋杉、木麻黃及台灣櫸等具有較高之二氧化硫吸收能力；台灣櫸、黃連木、茄冬及小葉欖仁等具有較高之乙烯吸收能力；檉柳、台灣櫸、黃連木、木麻黃、檸檬桉及苦楝具有較高之二氧化氮吸收能力；而大葉桃花心木、黃金榕、大葉山欖、小葉南洋杉、海棗、檉柳、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 SO2, C2H4, and NOx) 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. The second-year project will continue with the first-year one with an additional mission to publish a handbook entitled “The fast-growing and high-pollutant-uptake trees for petrochemical industrial parks in Taiwan.” 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 SO2 uptake rates of them and found that among them Norfolk island pine, iron-wood, and Taiwan zelkova can do the better job. For C2H4 uptake measurement, Taiwan zelkova, Chinese pistache, Bishopwood (red cedar) and Madagascar almond showed the higher uptake rates. To NOx, the higher uptake rates were found on juniper Tamarisk, Taiwan zelkova, Chinese pistache, iron-wood, lemon eucaly, and china berry. Results also showed that Honduras mahogany, golden-leaf fig, Formosan nato tree, Norfolk island pine, date palm, juniper Tamarisk, Ceylon ardisia, silvery Messerschmidia, poonga-oil tree, and India laurel fig were salt tolerant species. The present study results will be applied in tree recommendation for petrochemical industrial parks in Taiwan to abate the air pollution. They will also be useful for Taiwan EPA and other organizations to select the right tree species for growing in polluted areas and neighborhood parks in Taiwan.
