摘要

本研究區域共分3個地區，分別位於臺糖打鐵農場、屏東科技大學內後山及屏東機場。研究目的為收集林園綠帶內植栽葉片滯塵量，以瞭解不同樹種對空氣污染物懸浮微粒(塵埃)留滯效果。經過二年乾溼季調查結果可知，2007年於臺糖打鐵農場，就單位面積所測得之塵埃量以印度紫檀及樟樹所得之塵埃量最高，分別為828472 μg/m2及749637 μg/m2。屏東科技大學後山地區以血桐及構樹等所得之塵埃量最高，分別為762569 μg/m2及716258 μg/m2。屏東機場道路兩旁之黑板樹與臺灣欒樹不同栽植距離之滯塵能力，均為距離道路愈近者可獲得較佳之滯塵量。2008年打鐵農場地區東側與西側兩側與屏東科技大學後山於2008年比較乾季與溼季之落塵量，各樹種均以乾季所測得之落塵量大於溼季時期。屏東機場則以水黃皮無論是栽植於道路旁距離之遠近，乾季所測得之滯塵量均大於溼季所測得之落塵量。比較三個試驗綠帶每公頃之滯塵量，以打鐵農場東側滯塵量大於西側；屏東機場南側滯塵量大於北側；學校後山則大於打鐵農場西側與屏東機場北側。

Research area in the present study was divided into three sites, they were located at Da-Tye farmland of Taiwan Sugar Company, campus of National Pingtung University of Science and Technology(NPUST), and the area of Pingtung Airport, respectively. The aim was to investigate dust deposition on the leaf surface of various trees planted for a green belt to understand the effect on the deposition of suspend atmospheric pollutants(dust). Results of the collection in both dry and raing seasons for two years were analyzed. In 2007, in Da-Tye farmland, mean maximum of dust deposited were ranked 828472 μg/m2 and 749637 μg/m2 by Pterocarpus indicus and Cinnamomum camphora respectively. In NPUST campus, amount of dust deposition collected by plant of Macaranga tanarius and Broussonetia papyrifera were 762569 μg/m2 and 716258 μg/m2 respectively. In the area of Pingtung airport, amount of dust deposited on leaves of Alstonia schlaris and Koelreuteria henryi along the both roadsides, receive more dust near road than farer one. In 2008, compared the dust deposition of dry and wet season, both east and west side on Da-Tye farmland, and NPUST campus, the amount of dust deposited of various species in dry season were more than wet. In the area of Pingtung
airport, amount of dust deposited on leave of Pongamia pinnata planted no matter how far from the road, in dry season the amount of deposited dust were lager than wet. Compared the three experimental sites, amount of dust deposited per hectare in east side of Da-Tye farmland were higher west, in the south side of Pingtung airport were more than north, in the NPUST campus were higher Da-Tye farmland west side and Pingtung airport north side.
