摘　　要：现有的重金属污染土壤修复技术中,植物提取是一种绿色、经济的修复技术,但受制于植物生物量小、生长速率缓慢、对重金属的活化能力有限等缺点,其修复效率较低。为此,国内外学者将螯合剂、表面活性剂、酸碱度调节剂、叶面肥等化学诱导剂用于强化植物提取,有效地提高了修复效率,取得了阶段性的进展。对化学诱导剂强化植物提取修复重金属污染土壤的研究进展进行了综述,总结了现阶段存在的问题,展望了今后的研究方向。In the existing remediation techniques,phytoextraction is a green and economic remediation technique,but it is constrained by the shortcomings of small plant biomass,slow growth rate and limited activation ability for heavy metals,its remediation efficiency is relatively low. For this reason,based on phytoextraction,domestic and foreign scholars used chelator,surfactant,acidifying or alkalizing agent,foliar fertilizer and other chemical inducers to strengthen phytoextraction,effectively improved the efficiency of remediation,and made periodical progress. The research progress of chemical inducers strengthen phytoextraction repairing heavy metal contaminated soil was reviewed,the existing problems at the present stage were summarized,and its future research direction was prospected.
