Environmental pollution affects the quality of pedosphere, hydrosphere, atmosphere, lithosphere and biosphere. Great efforts have been made in the last two decades to reduce pollution sources and remedy the polluted soil and water resources. Phytoremediation, being more cost-effective and fewer side effects than physical and chemical approaches, has gained increasing popularity in both academic and practical circles. More than 400 plant species have been identified to have potential for soil and water remediation. Among them, Thlaspi, Brassica, Sedum alfredii H., and Arabidopsis species have been mostly studied. It is also expected that recent advances in biotechnology will play a promising role in the development of new hyperaccumulators by transferring metal hyperaccumulating genes from low biomass wild species to the higher biomass producing cultivated species in the times to come. This paper attempted to provide a brief review on recent progresses in research and practical applications of phytoremediation for soil and water resources.
环境污染影响土壤圈、水圈、大气圈、岩石圈和生物圈的质量。在过去二十年里，人们为减少污染源以及修复被污染的土壤和水资源付出了巨大努力。与物理和化学方法相比，植物修复成本效益更高且副作用更少，在学术界和实际应用领域都越来越受欢迎。已确定有400多种植物具有修复土壤和水的潜力。其中，遏蓝菜属、芸苔属、东南景天和拟南芥属植物得到了最多的研究。人们还期望，生物技术的最新进展将在未来通过将金属超积累基因从低生物量的野生物种转移到高生物量的栽培物种，从而在开发新的超积累植物方面发挥重要作用。本文试图简要综述植物修复在土壤和水资源研究及实际应用方面的最新进展。
