德州市深层地下水水化学动态演化

Dynamic Evolution of Hydrochemistry in Deep Groundwater in Dezhou City

摘要:

通过分析德州市德城区、临邑县城、武城县城、齐河县城和禹城市5个代表点深层地下水近20年或近10年的水质资料，研究了深层地下水的水化学类型和主要水化学指标的动态演化。研究表明，德城区、武城县和禹城县深层地下水水化学类型比较稳定，临邑和齐河个别年份的水化学类型发生变化，但水质并未发生实质性的改变；多数水化学组分含量呈上升趋势，但变化幅度相对较小。水化学组分含量发生变化的原因主要是由其自身水化学地球环境影响所致。

Abstract:

By analyzing the data of water quality of deep groundwater in the past 20 years or 10 years in Decheng district of Linyi county, Wucheng county, Qihe county and Yucheng county of Dezhou city, hydrochemical types of deep groundwater and dynamic evolution of main hydrochemical indexes have been studied. It is showed that hydrochemical types of deep groundwater in Decheng district, Wucheng county and Yucheng county are relatively stable, while in Linyi county and Qihe county have changed in some years, but the water quality has not changed substantially. The contents of most hydrochemical components show an upward trend, but the change range is relatively small. The change of hydrochemical composition is mainly due to the influence of its own hydrochemical earth environment.
