摘要
我国城市土壤重金属污染形势严峻,已经严重威胁到人类健康,因此受到普遍关注。木本园林植物是城市绿化、建设的主体,是城市生态系统中富有生命力的单元。植物能绿化、美化环境但不会进入食物链,可以对重金属污染土壤进行持续修复,已成为城市土壤污染植物修复的重要研究领域。该研究综述了近年来用于重金属污染土壤修复的木本园林植物,对其修复土壤的强化措施进行了探讨。重点阐述了木本园林植物对各种重金属的富集效应,对其耐受性和净化土壤重金属污染的应用潜力进行了分析,并对未来的发展方向进行了展望。
The situation of heavy metal pollution in urban soil in China is severe, which has seriously threatened human health, so it has been widely concerned.Woody garden plants have become an important research field of phytoremediation because of continuous remediation of heavy metal contaminated soil.Moreover, woody garden plants are the main body of urban greening construction, the vital unit of urban ecosystem, greening and beautifying the environment, especially will enter the food chain.In this study,the wood gardening plants used for remediation of heavy metal contaminated soil were reviewed,and the strengthening measures for remediation were discussed.This study focused on the enrichment effect of woody garden plants on various heavy metals,analyzed their tolerance and application potential of purifying soil heavy metal pollution,and forecasts the future development direction.
