中文摘要:地下水作为人类重要的水源之一,已经受到了人类活动的明显影响而造成污染,深入研究地下水化学特征及形成机制,对于地下水资源的合理利用具有重要意义。东汶河沂南地区分布着多种类型的含水层,并且农业、养殖业发达,是进行人类活动影响下的地下水水化学形成研究的理想地区。本文综合利用Piper三线图、离子比值法及数理统计方法(相关性分析、因子分析、聚类分析)等方法,对东汶河沂南地区地下水水化学特征及形成机理进行研究。研究结果表明,本区地下水水化学类型总体以HCO3-Ca、HCO3-Ca?Mg型为主,TDS含量在243~1473mg/L之间。地下水中HCO3-、SO42-、Ca2+和Mg2+等离子主要来自于碳酸盐类矿物及硫酸盐类矿物的溶解,而Na+、K+、Cl-、NO3-则主要来自于岩盐溶解和人类活动污染的影响。水岩作用的对地下水水化学的影响超过了62.024%;人类活动影响明显的水样占到了总水样数的13.6%,对地下水水化学的贡献率则达到了20.318%。河谷平原地区受到农业及养殖业等人类活动的污染明显。

Abstract:As one of the most important water sources, groundwater has been significantly affected by human activities. It is of great significance for the rational utilization of groundwater resources to study the chemical characteristics and formation mechanism of groundwater. Various types of aquifers are distributed in in Yinan of East Wenhe River Basin, and agriculture and aquaculture are well-developed. Therefore, this area is an ideal area for the study of formation of groundwater hydrochemistry under the influence of human activities. In this paper, the Piper diagram, ion ratio method and mathematical statistical methods (correlation analysis, factor analysis, cluster analysis) and other methods are used to study the groundwater hydrochemical characteristics and formation mechanism of the study area. The results show that the groundwater hydrochemical types are mainly HCO3-Ca and HCO3-Ca?Mg, and the TDS content is between 243 and 1473 mg/L. The HCO3-, SO42-, Ca2+ and Mg2+ in groundwater mainly come from the dissolution of carbonate minerals and sulfate minerals, while Na+, K+, Cl- and NO3- mainly come from the dissolution of halite and the pollution of human activities. The effect of water-rock interaction on groundwater hydrochemistry exceeds 62.024%. The number of groundwater samples with obvious influence by human activities account for 13.6% of the total groundwater samples, and the contribution of anthropogenic impacts to groundwater hydrochemistry reaches 20.318%. The river valley plain is obviously polluted by human activities such as agriculture and aquaculture.
