摘要
植物修复是当前修复镉(Cd)污染耕地土壤的重要方法之一,而如何平衡土壤修复效果和经济效益是应用推广植物修复技术的关键。文章在提出收益型植物修复概念的基础上,按用途将收益型植物分为3类:非食用型、可安全食用型和可选择进入食物链型,分类综述不同类型收益型植物对Cd污染耕地土壤的修复效果,以及修复过程中产生的修复成本、经济效益,以期为Cd污染耕地土壤植物修复推广和种植结构调整选取合适的替代作物提供参考。
Phytoremediation is essential for remediation of cadmium (Cd) contaminated cultivated soil,while balancing the effect of soil remediation and economic benefit is key to application and popularization of phytoremediation technology.Herewith,this review proposed a concept of profitable phytoremediation.According to utilization purpose,profitable plants were divided into three categories: non-edible,safe edible,and optional edible,and their remediation ability among common profitable plants were summarized,as well as their planting cost and economic benefit.This will provide a reference for popularizing phytoremediation toward Cd contaminated cultivated soil and screening suitable alternative crops for planting structure adjustment.
