The invention relates to a plant remediation technology for soil polluted by heavy metals of copper, lead and zinc, and discloses a method for remediation for a soil polluted by copper, lead and zinc by utilizing eucalyptus grandis of Myrtaceidites. In the technology, the eucalyptus grandis is planted in the soil polluted by the heavy metals of copper, lead and zinc, and the accumulated heavy metals of copper, lead and zinc are absorbed by virtue of the enrichment characteristic of the plants of the eucalyptus grandis on the copper, lead and zinc, and are transported to the overground parts of the plants; and the plants are intermediately cut by 50% after being planted for two years and completely cut after being planted for four years, an ashing treatment is performed and the heavy metals are extracted, so as to achieve a purpose of remediation for the soil polluted by the copper, lead and zinc. The eucalyptus grandis is one of the three fast-growing tress species in the world, as well as is high in biomass, flourishing in root system, and capable of absorbing and holding lots of heavy metals and water, so as to play roles in preventing the dispersion of pollution and raising the virescence level of polluted districts.
