设施菜地土壤重金属污染源解析技术研究进展.

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.
