鲁西南地区地下水锰的分布特征及其成因

摘要

In order to understand the content and origin of manganese in groundwater in southwest region of Shan-dong province, after collecting and analyzing 276 groups of groundwater samples and 18 groups of surface water samples, it is showed that the content of manganese in shallow groundwater in southwestern plain is in undetected to 2. 84mg/L, average concentration is 0. 35mg/L, and over standard rate is 41%. Content distribution of manganese in groundwater has close relation with the degree of industrialization, filling, runoff and discharge conditions in this region. Top soil, flow conditions of groundwater, aquifers media and salinity of underground water are main factors affected the distribution of manganese.%为了解鲁西南地区地下水中锰的含量及其成因,采集并分析了276组地下水样和18组地表水样,结果表明,鲁西南平原区浅层地下水中锰含量在未检出至2.84 mg/L之间,平均浓度为0.35 mg/L,超标率达41%。鲁西南地区地下水中锰含量的分布与该区的工业化程度以及所处的补、径、排条件密切相关。影响地下水中锰含量分布的因素主要有表层土壤、地下水径流条件及含水层介质和地下水矿化度等。
