碩士 === 國立屏東科技大學 === 森林系所 === 97 === 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.
