計畫中文摘要	本計畫場址位於屏東縣九如鄉，主要污染物為鋅、鉻、銅、鎳及總石油碳氫化合物（TPH）。計畫自101年起執行迄今，主要目的在於以生物復育法(蚯蚓與石化分解菌)與植生復育法(白楊、構樹、血桐、太陽麻與牛筋草)改善污染。在場址內共設置六個試驗區，除對照區外，另設有三個生物復育區與二個為植生復育區。在三年餘的試驗後發現，各復育區之TPH濃度多呈現降低趨勢，三個生物復育區土壤中之TPH濃度減量百分比介於33％～97％，植生復育區則為19％～81％；而重金屬之測值指出，各復育區同一土層之濃度呈現無規則變化，不過，多數土層中之污染物濃度仍高於土壤污染管制標準。其次，生理試驗結果顯示，除白楊因正值落葉期以致光合潛力較差外，其餘植物已能適應污染環境。此外，本年度進行之木本及草本植體重金屬測值顯示，所有復育植物都具吸收累積效果，其吸收量依序為Zn＞Cu＞Cr＞Ni。最後以所有復育植物修剪或收成 植體之生質量與重金屬濃度計算其吸收移除量，藉以評析植生復育效益，結果發現總移除量為Zn（618.1 g）＞Cu（12.07 g）＞Cr（11.39 g）＞Ni（10.07 g），至於復育植物對重金屬之移除能力，木本植物依序為白楊＞血桐＞構樹，而草本植物則為牛筋草＞太陽麻。
計畫英文摘要	The contaminated site proposed in this study is located at Jiuru Township, Pingtung County, with an area of 1,800 m2. According to previous investigations, the major contaminants in soils were found to be zinc, chromium, copper, nickel and total petroleum hydrocarbon (TPH). The objective of this research project is to conduct remediation in the contaminated site. Five treatment plots were designated in the highly contaminated area, in which three were designed for bio-phytoremediation (BP1, BP2, and BP3) and two for phytoremediation practice (PR1 and PR2). One control plot was used for comparison purposes. Since the initiation of this study in 2012, earthworm (E. fetida) and petroleum-degrading bacteria (Pseudomonas sp. NKNU01) have been utilized for bioremediation, while Poplars (Populus bonatii Levl.) and Sun Hemp (Crotalaria juncea L.) in the phytoremediation practice. Selective native plants, namely Macaranga (Macaranga tanarius) and Papermulberry (Broussonetia papyrifera) have also been planted to evaluate their remedial capabilities in 2014, while a dominant weed Eleusine indica was chosen for the same evaluation this year. The results of soil analysis showed a trend of decreasing TPH concentrations in most treatment plots, and the removal rate of TPH within the three bio-phytoremediation plots ranged from 33％～97％ and from 19％～81％ in the two phytoremediation plots. However, heavy metal concentrations were not significantly reduced and thus most soils were still highly contaminated. Plant growth and physiological investigations indicated that Poplars, Papermulberry and Macaranga were adaptable to the pollutants. For the purpose of further explorations, biomass and heavy-metal contents of the studied plants were analyzed to evaluate the removal efficiency of heavy metals. The results indicated that the four metals were absorbed and removed by all studied plants in the order of Zn（618.1 g）＞Cu（12.07 g）＞Cr（11.39 g）＞Ni（10.07 g）.The heavy-metal removal ability of the woody plants was found to be Poplars＞Macaranga＞Papermulberry and Eleusine indica＞Sun Hemp for the herbaceous plants.
