摘　　要：宿迁处于黄淮泛滥平原区过渡地带,地质条件复杂,地下水中砷在该地区的分布及演化特征受到多重环境的影响,砷在该地区的富集机制目前仍无明确结论。该文基于不同时期对废黄河下游苏北地区宿迁段进行的多次地下水质调查,分析了砷的空间分布特征,基于原生和水土本底情况,对原生地质环境对地下水中砷的影响及砷的存在形式、迁移因素等进行了研究。探究了地下水中砷变化过程的形成机理。研究成果拟为该地区后续的地下水合理利用与管理提供科学依据。Suqianarea is in the transition zone of the Yellow-Huaihuai floodplain area,with complex geological conditions.The distribution and evolution characteristics of As in groundwater are affected by multiple environments,and the enrichment mechanism of As in this area is still unclear.Based on the investigation of groundwater quality in Suqian section of the downstream of the waste Yellow River at different periods,the spatial distribution characteristics of arsenic were analyzed.Based on the primary and soil and water background,the influence of the primary geological environment on arsenic in groundwater,as well as the existing forms and migration factors of arsenic were studied.The formation mechanism of As variation in groundwater was investigated,which providing scientific basis for the rational utilization and management of groundwater in this area.
