土壤污染的植物修复技术:现状与前景

Phytoremediation of contaminated soils:status and prospect

随着世界人口的快速增长(预计到2013年全球人口将达到70亿)和工业的迅猛发展,土壤这一人类赖以生存的必需资源正承受着越来越大的压力。因受到工业三废和农用化学品以及矿区的污染,有相当数量农田的土壤质量日趋下降。土壤污染的植物修复(即利用绿色植物来去除环境中的污染成分或将其转化为无毒的物质的过程)近年来受到世界各国的瞩目,并取得了很大的进展。本文综述了这一领域的近几年来的研究现状和发展趋势。

Contaminated biosphere caused by various pollutants is a major environmental and human health concern now days with the global population increase and industrial development.To combat the degrading environment phytoremediation is considered as a simple and cost-saving measure,which has been attracting more and more attention of scientists in many fields.Here the status and prospect of this promising technique is reviewed briefly.
