摘要: 利用物理、化学方法修复有机污染环境,费用昂贵,而且还可能使当地的生态资源难以再利用,对于大面积污染土壤也难以实施。植物修复,利用植物吸收、降解以及根际圈降解的作用方式将有机污染物从环境中彻底去除,具有处理费用相对低廉、对环境扰动少和使资源可持续利用的特点,目前已成为环境科学领域的一大热点和前沿。本文对环境中主要有机污染物的发生机理、近年来植物修复有机污染的研究进展做一综述,并对有机污染植物修复的强化措施进行了展望。

Abstract: Phytoremediation is a kind of technology which can thoroughly remove organic pollutants from contaminated sites through phytoextraction, phytodegradation, and rhizosphere biodegradation. In contrast to many physical and chemical remediation technologies which are hardly used to clean organic pollutants- contaminated soil in large area because of their expensive cost and potential destruction to polluted environment, phytoremediation has the advantages of relatively lower cost, smaller environmental disturbance, and reuse of natural resources, and has been one of the hot spots and frontiers of environmental science. This paper reviewed the contamination mechanisms of main organic pollutants in environment and the recent studies on phytoremediation, and gave prospects on the strengthening methods of organic pollutantsphytoremediation.
