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(白楊與太陽麻)改善污染，本年度並栽植本土植物 構樹、血桐與田青，且評析其復育效果。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植生復育區。在三年的試驗後發現，各復 育區之TPH濃度雖仍有高低之不規則變化，但大體上呈現降低趨勢，多數處理區 都有不同比例之減量效果，三個生物復育區土壤中之TPH濃度減量百分比介於19 ％～94％，植生復育區則為43％～97％。其次，重金屬之測值指出，在各復育 區同一土層之濃度呈現不規則變化，且多數仍高於土壤污染管制標準。此外， 所有復育植物之生育調查與木本植物之生理試驗結果顯示，各類植物之生長與 生理狀況正常，可以忍受並適應污染環境，皆可做為本場址之復育植物；而植 體之重金屬測值指出，各類植物皆具吸收累積效果，其累積量依序為Zn＞Cu＞ Ni＞Cr。最後以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，所有復育植物全年之總移除量依序為Zn（283 g）＞Cu （2.03 g）＞Ni（1.78 g）＞Cr（1.22 g）。至於三種木本植物對重金屬之移除能 力依序為白楊＞血桐＞構樹。
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 m 2 . 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 biophytoremediation (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. This year, selective native plants, Macaranga (Macaranga tanarius), Papermulberry (Broussonetia papyrifera) and Indian Sesbania (Sesbania cannabiana), have also been planted to evaluate their remedial capabilities. Results of soil analysis showed that the removal rate of TPH within the three bio-phytoremediation plots ranged from 19％～94％ and from 43％～97％ 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 all plants were vigorous and adaptable to the pollutants. For the purpose of further explorations, the 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（283 g）＞Cu（2.03 g）＞Ni （1.78 g）＞Cr（1.22 g）. Finally, the heavy-metal removal ability of three woody plants was found to be Poplar＞Macaranga＞Papermulberry
