摘    要:我国土壤重金属污染形势严峻,直接威胁着人类健康,受到普遍关注,各种重金属污染土壤修复技术成为研究热点。植物修复技术因其安全、廉价,被认为是修复重金属污染土壤较好的措施之一,其中园林植物具有美化环境、不进入食物链及可带来环境效益等优势而成为植物修复领域的研究热点。该研究通过文献资料查阅,阐述了近年来关于园林植物对我国主要重金属污染土壤的修复效果,并从园林植物种类、富集特性、耐受性和环境效益几个方面进行了分析,最后,对进一步开发园林植物修复重金属污染土壤的研究方向进行了展望,为重金属污染土壤园林植物修复研究与应用提供参考。

关 键 词:园林植物  重金属  土壤修复

Abstract:Heavy metal pollution in China is threating to human health seriously,and all kinds of heavy metal contaminated soil restoration techniques have attracted more attention. Phytoremediation technology is considered to be one of the best measures to repair heavy metal contaminated soil because of its safety and cheapness. The garden plants have the advantages of beautifying the environment,not entering the food chain and bringing environmental benefits,and thus the restoration of the heavy metal contaminated soil by the garden plants has become a focus. This study expounded the restoration effect on the main heavy metal contaminated soil in China in recent years based on the literature review. Then we analyzed the restoration effect of garden plants which from the aspects of plant species, enrichment characteristics, tolerability and environmental benefits. Finally, we prospected the research direction of the further development of garden plants for remediation of heavy metal contaminated soils, which provided reference for the research and application of garden phytoremediation of heavy metal contaminated soil.
Keywords:garden plants  heavy metals  soil remediation
