泗水县尖山村岩溶水化学特征时空变迁及影响分析

Temporal and Spatial Changes of Ion Concentration in Karst Water in Jianshan Village, Sishui County and its Impact Analysis

通过对泗水县尖山村天然矿泉水水井2015、2016、2020、2021年水样采集,对比分析了近7年的地下水溶解性总固体、氯离子、硝酸根等离子变化特征进行分析评价。结果表明,地下水中溶解性总固体、氯离子、硝酸根离子等指标呈逐年缓慢升高的趋势,有水质逐步变差的趋势,造成地下水离子浓度变化主要是人类活动强度增大对地下水化学场造成的影响。

Through collecting water samples from natural mineral water wells in Jianshan Village,Sishui County in 2015,2016,2020 and 2021,the change characteristics of dissolved total solids,chloride ions and nitrate ions in groundwater in the past seven years were analyzed and evaluated.The results showed that the indicators of dissolved total solids,chloride ions and nitrate ions in groundwater showed a trend of slowly increasing year by year,with a trend of gradual deterioration of water quality.The change of groundwater ion concentration is mainly caused by the increase of human activity intensity and the impact on groundwater chemical field.
