摘要
基于山东莱芜地区2021年9月泉水普查取样水化学数据,运用数理统计、相关性分析、Piper三线图、Gibbs图及离子比值分析等方法,总结了泉水水化学特征,对其形成机制进行分析.结果表明,泉水整体呈弱碱性,阳离子以Ca^(2+)为主,阴离子以HCO_(3)−为主,TDS在152.75—982.64 mg·L^(−1)之间,平均值为423.15 mg·L^(−1),为低矿化度水;区内泉水水化学类型以HCO_(3)^(-)Ca型、HCO_(3)·SO_(4)-Ca型、HCO_(3)^(-)Ca·Mg型为主,局部呈点状差异分布;泉水中离子主要来源于水岩相互作用,碳酸盐岩和硅酸盐岩矿物溶解是主要离子来源.同时,区内泉水受人类活动影响明显,NO3−主要来自于农业活动.本研究可为莱芜地区泉水保护与合理规划利用提供依据.
Hydrochemical characteristics of spring are summarized and analyzed its formation mechanism using mathematical statistics,correlation analysis,Piper trigram,Gibbs chart and ion ratio analysis according to hydrochemistry results of spring water survey project that is conducted in study area in September 2021.The results show that spring is weakly alkaline,which dominant cation and dominant anion is Ca^(2+),HCO_(3)−respectively.TDS of spring ranges from 152.75 mg·L^(−1)to 982.64 mg·L^(−1)with average of 423.15 mg·L^(−1).Hydrochemical types of spring are mainly HCO_(3)^(-)Ca,HCO_(3)·SO_(4)-Ca,HCO_(3)^(-)Ca·Mg while other type distributes locally.Ion sources of spring is water-rock interaction primarily including dissolution of carbonates and silicates.In addition,spring is also affected by anthropogenic activities,especially nitrates from agricultural activities.This research results can provide scientific and technical guidance for spring protection and rational planning and utilization in Laiwu area.
