Phytoremediation is recognized as an environmentally, economically and socially efficient phytotechnology for the reclamation of polluted soils. To improve its efficiency, several strategies can be used including the optimization of agronomic practices, selection of high-performance plant species but also the application of amendments. Despite evidences of the benefits provided by different types of amendments on pollution control through several phytoremediation pathways, their contribution to other soil ecosystem functions supporting different ecosystem services remains sparsely documented. This current review aims at (i) updating the state of the art about the contribution of organic, mineral and microbial amendments in improving phytostabilization, phytoextraction of inorganic and phytodegradation of organic pollutants and (ii) reviewing their potential beneficial effects on soil microbiota, nutrient cycling, plant growth and carbon sequestration. We found that the benefits of amendment application during phytoremediation go beyond limiting the dispersion of pollutants as they enable a more rapid recovery of soil functions leading to wider environmental, social and economic gains. Effects of amendments on plant growth are amendment-specific, and their effect on carbon balance needs more investigation. We also pointed out some research questions that should be investigated to improve amendment-assisted phytoremediation strategies and discussed some perspectives to help phytomanagement projects to improve their economic sustainability.
植物修复被认为是一种在环境、经济和社会方面都高效的用于修复污染土壤的植物技术。为提高其效率，可采用多种策略，包括优化农艺措施、选择高性能植物品种以及施用改良剂。尽管有证据表明不同类型的改良剂通过多种植物修复途径对污染控制有益，但其对支持不同生态系统服务的其他土壤生态系统功能的贡献仍鲜有文献记载。本综述旨在：（i）更新关于有机、矿物和微生物改良剂在改善植物稳定化、无机污染物的植物提取和有机污染物的植物降解方面的贡献的最新研究状况；（ii）综述它们对土壤微生物群落、养分循环、植物生长和碳固存的潜在有益影响。我们发现，在植物修复过程中施用改良剂的益处不仅限于限制污染物的扩散，还能使土壤功能更快恢复，从而带来更广泛的环境、社会和经济收益。改良剂对植物生长的影响因改良剂而异，其对碳平衡的影响还需要更多研究。我们还指出了一些为改进改良剂辅助植物修复策略而应研究的问题，并讨论了一些有助于植物管理项目提高其经济可持续性的观点。
