摘　　要：锶在地下水营力作用下迁移和转化,其富集特征具有重要的水文地球化学意义,且与人类健康及生态环境密切相关,因此其分布特征及富集成因值得关注。在掌握研究区基本背景的前提下,采集地下水样品进行锶含量分析测试,刻画该区地下水中锶的质量浓度水平,研究不同空间位置、浅/深层含水层系统中锶的分布,以及与处理塘、滞洪区水样中锶分布之间的关系。分析本区锶富集的水文地球化学环境特征,在此基础上运用R-型因子分析法,结合区域地层矿物成分分析及土(粪)样锶含量测试结果,明晰该区水文地球化学环境形成的控制作用,探索锶富集的形成原因。结果显示:该区水文地球化学环境与所处干旱半干旱松嫩低平原大区域环境特征有一致性规律,区内地下水中锶富集程度较高,平均质量浓度达1.17mg/L,且锶富集成因由水岩作用和非点源污染共同控制。The fate and transport of Strontium are controlled by groundwater agent in geological environment.Since Sr enrichment is of hydro-geochemical significance and also closely related to human and eco-environmental health,the distribution features and enrichment mechanism deserve studying.Based on physical setting of the study area,the groundwater was sampled and Sr concentration in groundwater was analyzed to characterize the Sr enrichment extent,the spatial distribution features in the shallow/deep groundwater at different locations and the relationship among several water bodies.Based upon the hydro-geochemical environmental condition,R-factor analysis method was coupled with soil sample analysis to determine the characteristics of the specific hydro-geochemical environment and fate/transport of Sr.The results indicate that the local hydro-geochemical environment in the study area was consistent with the regional arid-semiarid area in the Songnen Low Plain,and notable Sr enrichment in groundwater was revealed with a high level of 1.17 mg/L.In addition,Sr enrichment was controlled by both water-rock interaction and non-point pollution.
