Abstract: Heavy metal contaminated soil remediation is a difficult problem in today's global ecological restoration.Phytoremediation is a promising choice for the treatment of heavy metal contaminated soil because of its cost-effective and environmentally compatible characteristics.Hyperspectral remote sensing technology can obtain the physical and chemical parameter information of vegetation growth in a high-efficiency,non-destructive and real time manner.It provides technical support for evaluation of the effects of phytoremediation.The application progress of hyperspectral remote sensing technology in phytoremediation are described,and estimation models of vegetation physicochemical parameter of heavy metal contaminated soil is discussed. Besides that,the estimation models based on differential spectrum,"three-sided" parameters and vegetation index are analyzed and compared,so as to provide reliable reference of evaluating the effects of phytoremediation in mining areas.

Key words: Hyperspectral remote sensing, Phytoremediation, Heavy metal contaminated
