摘要:

本文全面综述了重金属在土壤–植物系统中的存在规律,分析了农作物中重金属污染物的来源、迁移、转化及富集规律,归纳了土壤理化性质、农作物生理生化因素对土壤重金属生物有效性的吸收转化的规律,剖析了重金属生物有效性的影响因子,进而对近年相关关系研究方法进行论述。最终提出今年土壤–植物系统研究中存在的薄弱环节,提出进一步研究区域环境中土壤–农作物系统重金属空间对应关系、影响机制和定量模型。

This paper comprehensive reviewed the existing laws of heavy metals in soil-plant system, analyzed the source, migration, transformation and enrichment regularity of heavy metal pollutants in soil plant system, summarized the effect of physicochemical properties of soil and crop physio-logical-biochemical factors on heavy metal bioavailability in soil-crop system, dissected the relating factors, and discussed recent related research methods. This study finally submitted the weak link in the system, and proposed the further research in spatial relationship with different heavy- metals, influence mechanism and quantitative model.
