Abstract:
As a result of human activities such as mining and smelting of metalliferous ores，electroplating，energy and fuel production，and fertilizer and pesticides of intensive agriculture，the soil polluted by heavy metals，and the serious consequences are brought about.Because the plants have resistance，avoidance，bioaccumulation and hyperaccumulation to heavy metals，it is possible for using plants to remediation the contaminated soil by heavy metals and utilizing these polluted soils to produce production.However，the natural hyperaccumutors have the endemic features，and differed among plant species.At the same time，these plants have the limited level of heavy metals concentration，thereby，the phytoremediation cost long time to remediation the polluted soils by heavy metals.The concept of ‘environmental breeding’ was first put forward in the paper.Then the bases of ‘environmental breeding’ were discussed.Therefore the ‘environmental breeding’ will have the broad application prospects.In order to accelerate the phytoremediation speed，the environmental breeding will be imminent.
