The plan for the third phase, the management and maintenance for the dominant species within the site.Focus on the site of the regular weeding, fertilization, watering and equipment maintenance, regular replanting and regular site inspections. Systematic implementation of the operations, to achieve the site green and inhibit the proliferation of pollution and other effects. From 102 to 105 for the results, the phytoextraction species including Swietenia macrophylla, Salix warburgu. show various efficiency of phytoextraction in Zn with the maximum concentrations of 263 and 363 mg/kg respectively.The phytostabilization species Vetiveria zizanioides show a good ability in fixing the metals in their roots to minic the metals leaching and diffusion at the site. The maximum concentrations of Cr, Ni, and Zn in the roots are increase. The heavy metal pollution in this site is concentrated in the south and the center of the site, with the highest concentration of Pb, followed by Cu>Zn>Ni>Cr>Cd. In the implementation of the plan also assessed carbon reduction remediation, The total harvest of the phytoextraction for large-scale removal at this site is about 38.73 tons and the fixed carbon quality is estimated at about 15.49 tons. According to the implementation of the status of the plan, the future of the project if the implementation of the ongoing analysis of the premise, the operation and maintenance costs estimated at about 0.52 million NTD.Although the phytoremediation is a long time of the rehabilitation technology, but the rehabilitation of plant remediation is still a low-cost and non-destructive way to be followed by the development of low-cost, low pollution remediation method and then replaced.
