煤炭资源型城市浅层地下水化学特征及成因分析
Hydrochemical characteristics and genetic analysis of shallow groundwater in coal resource-based cities
摘要
Abstract
Under the background of carbon peak and carbon neutrality,the hydrochemical characteristics and genesis of ground-water are crucial for the evolution and transformation of industrial structures in coal resource-based cities.Jining City,Shandong Province is a typical city integrating mining and urban spaces.This study analyzes the hydrochemical characteristics of shallow groundwater in the urban areas of Jining City and its formation mechanism and control factors.The results showed that the overall groundwater was alkaline hard water,and the hydrochemical types tended to transform from HCO 3-Ca·Mg and HCO3-Na·Ca to HCO3·SO4-Ca,HCO3·Cl-Ca·Mg,HCO3-Na·Ca·Mg,HCO3·Cl-Na·Ca.The main controlling factor of hydro-chemical composition in the study area was water-rock interaction,and its hydrochemical characteristics were mainly affected by carbonate karst filtration,agricultural production,and fluorine bearing mineral leaching.The impact of industrial and mining distri-bution on shallow groundwater in the study area was gradually increasing.This study can provide some reference for the reasonable development and utilization of local groundwater.关键词
