设施菜地土壤重金属污染源解析技术研究进展

Research advances in the source apportionment techniques of heavy metal pollution in soil of greenhouse vegetable fields

设施蔬菜栽培是当前主流种植方式之一。因为设施菜地常年处于一种高温、高湿、高肥料投入的半封闭状态,其土壤重金属污染问题突出。由于土壤环境介质的复杂性、重金属污染来源的多样性以及分布的特异性,国内外学者对土壤重金属源解析方法尚未建立起一个全面和详尽的体系,针对设施菜地中重金属污染源解析研究的相关报道也较少。文章综合论述了国内外设施菜地重金属源解析应用情况,并针对现有设施菜地重金属定量源解析应用较少的情况,筛选适用方法及其优缺点进行概述,同时对设施菜地中重金属源解析方法研究的未来发展进行展望,为能够从源头解决设施菜地重金属污染问题提供技术支持。

Greenhouse vegetable production is currently one of the main agricultural planting methods.The heavy metal pollution is the relatively prominent problem in the greenhouse vegetable field which is under a semi-closed state with high temperature,high humidity and high fertilizer input.Due to the complexity of soil environment,and the diversity of sources and the specificity of distribution of heavy metal pollution,a comprehensive and detailed system for the source apportionment of heavy metals in soils has not been established.Little is reported in literature on the source apportionment of heavy metal pollution in greenhouse vegetable fields.In this paper,the application of source apportionment of heavy metals in greenhouse vegetable fields was reviewed based on the related literature.In view of the limited application of quantitative source apportionment of heavy metals in greenhouse vegetable fields,several suitable methods were recommended and their advantages and disadvantages were summarized.Meantime,the prospect of the research on the source apportionment methods of heavy metals in greenhouse vegetable fields was put forward,so as to provide the technical support to solve the problem of heavy metal pollution in greenhouse vegetable fields from the source.
