摘要註:	本研究主要目的為使用整合型方法教蜇合劑、植物生長激素與過氧化鈣，添加至含有重金屬土壤，利用能源作物向日葵吸收重金數並累積於植物體內，減少土壤中重金屬含量，達到植生復育的訴求。實驗主要分下列四部分:(1)植栽實驗，探討在重金屬銅、鋅、鉛土壤中添加蜇合劑(EDTA、EDDS)、植物生長激素(GA3、IAA)與過氧化鈣，其植生復育之最適操作參數；(2)管柱型盆栽實驗，由於蜇合劑的添加會增加土壤中重金屬的流動性，對於地下水環境(地下水)可能會造成二次污染的問題，估計對不同土曾在一般澆灌與降雨情形下，對出流水重金屬濃度進行分析，評估影響之可能性；(3)模槽實驗，由盆栽實驗所得植生復育最適操作參數與管柱型盆栽實驗對於地下環境之探討，將整合型之方法應用於模槽中，其植生復育成效與盆栽實驗成果相比較，評估應用於實廠之可行性。故實驗結果顯示，盆栽實驗在重金屬銅、鋅下以GA3+EDDS+CAO2組最適合，而重金屬鉛則以GA3+EDTA+CAO3組最適合。接著管柱型盆栽實驗中得知，在一般澆灌情形下，對於地下環境並無危害之疑慮，相對的在降雨情形下，其降雨強度的多寡攸關土壤內孔隙飽和時間，降雨持續時間的長短，則影響重金屬汙染地下水環境的嚴重性。而整合上述兩者應用在模槽實驗，證明了向日葵在生長情況與對重金屬汙染之吸收與累積量都達到盆栽實驗最適操作下之效率，所以整合型植生復育適合應用於實場上。 The purpose of this research is to verify a set of intergrated measures for the phytoremediation of soil polluted by heavy metals. With the addition of chelant, phytohormone and calcium peroxide into the soil, we then grow the energy cro[s, i.e. sunflowers, on it, aborsbing heavy metals into the plant's body, reducing their content level and consequently achieving the goal of phytoremediation. There are four major parts of this proven experiment: First, the pot experiment, used to investigate the optimal operational parameters of the to-be-added chelant (EDTA, EDDS), phytohormones (GA3 and IAA) and calcium peroxide for the phytoremediation of the soil polluted by heavy metals like copper, zinc and lead. Secondly, the colum-type pot experiment is used to analyze the heavy metal concentration of the effluent flowing out of different soil layers under normal irrigation and precipitation since the addea chelant would enhance the liquidity of heavy metals in the soil, which might cause secondary pollution to the unferground environment from the first two eaperiments. By comparing its phytoremediation performance with the results of the pot experiment, we can then evaluate its feasibility in applying the integrated measures to real fields. The pot qxperiment results indicate that hte combination of GA3+EDTA+CAO2 is the most suitable one for eliminating lead from the soil. From the results of the column-type pot esperiment, we have learned that the integrated measures cause no harm to the underground environment under normal irrigation. However, the rainfall intensity can directly influence how long the pores of the soil will be saturated; the rainfall duration has a significant impact on the severity of heavy metal pollution of the underground environment. Finally, the growing conditions and the heave metal absorption of the sunflowers in the through reached the same level as the ones in the pot experiment. Therefore, the integrated measures have been proved suitable for the phytoremediation of real fields.
