[目的]为了研究天津市南部地区复垦地土壤汞元素的含量特征,促进土地复垦工作的进一步开展.[方法]建立了8个工作区,配套采集复垦地、残留建设用地、周边农用地的耕层土壤及土壤剖面,并且进行相关研究.[结果]复垦地土壤汞元素普遍低于周边农用地.农用地汞元素含量与农业生产关系密切.复垦地土壤剖面含量规律性不强,与周边农用地土壤剖面差异很大.[结论]应减少污水灌溉,使用重金属含量低的肥料,防止复垦地土壤汞元素的累积.

[Objective]The research aimed to find out the characteristics of Hg in reclaimed land,which would help promoting further land reclaimation work.[Method] 8 working areas where tilth soil and soil profile samples were taken from reclaimed land,and remained construction land,residual construction land and nearby farmland respectively were set up.And the related research was carried out.[Result] Hg in reclaimed land was generally lower than that in nearby farmland.There was correlation between Hg content and agricultural activities.Hg content in soil profiles from reclaimed land distributed irregularly,which was different from that in nearby farmland.[Conclusion] Avoiding Hg accumulation in reclaimed land by measures like reducing sewage irrigation and using fertilizer with low heavy metal concentration was suggested.
