中文摘要：

多环芳烃（PAHs）是一类广泛存在于天然环境中的持久性有机污染物,对土壤的污染尤为突出,给生态环境、植物和人类健康造成严重的潜在威胁.当前,修复受PAHs污染的土壤是国际土壤和环境领域研究的热点,而植物修复是最具潜力的环境修复技术之一.本文对近年来土壤PAHs及其与其他污染物复合胁迫对植物生长及其形态结构、光合作用和抗氧化系统等影响研究的最新进展进行综述,并对今后的重要领域和研究热点进行了展望.

英文摘要：

Polycyclic aromatic hydrocarbons （PAHs） are the ubiquitous organic persistent pollu- tants in natural environments （especially in soil）, giving serious potential risks to the eco-environ- ment, plants, and human beings. At present, the remediation of PAHs-polluted soil is one of the hot topics in the research fields of soil and environment. Phytoremediation is one of the environmen- tal restoration techniques with most potentiality. This paper reviewed the newest progress in the re- searches of the effects of soil PAHs pollution and its combined stress with other pollutants on the plant growth, morphological structure, photosynthesis, and antioxidant system, and prospected the important fields and hotspots of related researches in the future.
