安徽六安江淮分水岭地区地下水水化学特征分析

ANALYSIS OF FEATURES OF GROUNDWATER CHEMISTRY IN THE JIANGHUAI WATERSHED,LU’AN,ANHUI

六安市金安区红层广泛分布,资源型缺水严重。通过分析工作区地质、构造和水化学特征等方面,对该区地下水水化学特征及形成原因进行了分析和评价,结果表明工作区地下水主要接受大气降水的补给,地下水积极参与大气降水和地表水的循环,水质受环境影响明显。成果分析对本地区合理开发利用和保护地下水资源具有重要的指导意义。

Red layer is widely distributed in Jin’an District,Lu’an City,and the water shortage is serious in terms of resource.Based on the analysis of the geological,structural and hydrochemical characteristics of the working area,this paper analyzes and evaluates the hydrochemical characteristics of groundwater and how it formed in the area,and the results show that the groundwater in the working area is mainly fed by atmospheric precipitation,and the groundwater actively participates in the circulation of atmospheric precipitation and surface water,and the water quality is obviously affected by the environment.Analysis of the results is important to rational development,utilization and protection of groundwater resources in this area.
