天津市郊区菜地土壤重金属通量的研究
Heavy Metal Flux Research in Tianjin Suburb Vegetable Farmland
摘要
Abstract
[Objective] The research aimed to find out the characteristics of heavy metal input and output flux in Tianjin suburb vegetable farmland,which would help promoting the sustainable use of land resource.[Method] The research in 2 sites was carried out,where dry and wet atmospheric deposit,irrigation water,fertilizer and vegetable samples were collected.[Result] The heavy metal input flux of dry and wet atmospheric deposit was higher in industry area.The heavy metal output flux of vegetable was higher,where the heavy metal was more accumulated in soil.Dry and wet atmospheric deposit was the main heavy metal input resource of Tianjin suburb soil.Four heavy metal elements concentration in Tianjin suburb vegetable farmland soil was constantly increasing.[Conclusion] Remediation of contaminated soil and reduction of heavy metal input flux of dry and wet atmospheric deposit were important solutions to guarantee the sustainable utilization of suburb vegetable farmland.关键词
