奎屯河流域地下水水化学特征及成因分析
Chemical characteristics and genetic analysis of groundwater in Kuitun River Basin
摘要
Abstract
The analysis of groundwater chemical characteristics and their origins is essential for evaluating groundwater quality,identifying pollution sources,developing water resource management strategies,and safeguarding human health and the environ-ment.Based on a total of 78 groundwater samples collected at the same sites in the Kuitun River Basin in 2017 and 2023,the characteristics and causes of groundwater in this area were analyzed by Piper trilinear diagram,Gibbs diagram,saturation index(SI)method and ion ratio method.The findings indicated that:①There was a converging trend in the types of groundwater chem-ical characteristics in the Kuitun River Basin in 2023 compared to 2017,with cations transforming into Na type and anions into Cl type.② Rock weathering primarily influenced the piedmont diluvial inclined gravel plain and alluvial fine soil plain,while evapo-ration and concentration mainly affect the alluvial lacustrine fine soil plain with a tendency to increase.The ion components in the middle and lower reaches of the fine soil plain were predominantly derived from evaporative karst decomposition with an increasing trend,whereas those in the fore mountain diluvial inclined gravel plain originate mainly from carbonate and silicate mineral disso-lution.Strong adsorption by alternating cations has led to increased Na+concentration in downstream fine soil plains.Groundwater quality in northern alluvial fine soil plains as well as those around alluvial lacustrine fine soil plain within Kuitun River basin has exceeded China's drinking water standard,and about 10%of the water samples have surpass irrigation water standards in future.These research findings can serve as a reference for rational utilization and management of groundwater resources within Kuitun River Basin.关键词
