中文摘要：

近年来,用于重金属污染土壤修复的超富集植物对重金属吸收、转运、富集、解毒生理与分子生物学机制得到了深入研究,且有一定程度的田间实践。但对其完成重金属超富集起基础支撑作用的光合生理却涉及较少,尤其是在多种超富集植物联合修复方式下。本综述建议根据不同物种的生活史进行单种、套种、轮作、间作或/和混种,施以不同农耕（除杂草、水肥、松土、病虫害防治等）管理方式与多种强化萃取措施,进行物种间（垂直）群落结构的构建,对其单独和联合萃取土壤重金属效率进行比较,并同期测定植物光合作用参数,揭示植物光合响应机制。认为,以此可为以低生理代价来利用多种超富集植物提高土壤重金属污染的田间修复效率提供重要科学依据。

英文摘要：

In recent decades,the mechanism of absorption,transport,enrichment,detoxification physiology and molecular biology of hyperaccumulator plants remedying the heavy-metals-contaminated soils was exhaustively researched,mainly covering the following topics： rhizosphere activation,absorption,transport and enrichment mechanism of heavy metal,as well as a certain degree of field practice. However,little information was available for the photosynthetic physiology that plays an essential role in the phytoremediation of heavy-metals-contaminated soils,especially the joint use of multiply hyperaccumulator plants to remedy the contaminated soils. It is therefore proposed that,according to the life cycle of various species,different cultivation modes,including single cropping,interplanting,crop rotation,intercropping and/or mixed should be conducted,aided with normal farming management measures,strengthening extraction for heavy metal species,constructing vertical community structure of hyperaccumulator plants and measurement of various photosynthesis parameters. This review will facilitate the improvement of the efficiency of phytoremediation of heavy-metals-contaminated soils with low physiological costs.
