摘要
随着城市化和工业化的加速,土壤的重金属污染问题日趋严重。植物修复技术作为一种环境友好型治理措施,越来越受到人们关注。植物修复是利用某些植物对土壤重金属的超量吸收、挥发以及固定等特殊功能,并与根际微生物协同作用,原位修复污染土壤的方法,费用低、效果显著,是极具发展潜力的"绿色产业"。
With the acceleration of urbanization and industrialization, heavy metals contamination of soils becomes more and more serious. Phytoremediation is getting more attention as a environmental friendly control measure. Phytoremediation of the polluted soil is a kind of method to remedy the polluted soil. It uses plants to over-absorb and volatilize the heavy mental in the polluted soil, and uses the collaboration of plants and the microbe around the root to decompose the organic contamination in the original spot. Phytoremediation is a promising Green Industry, which has characteristic of low-cost and high-efficiency.
