| 中文摘要:广大的平原地区和主要城市地区地下水水质的变化状况可以说明，人类活动引起了河北平原地下水化学组分的改变，其中硬度是一个普遍升高，且超标的化学组分，因此，认为硬度是反映人类活动对地下水影响的特征性化学指标，人类活动引起地下水的明显污染可以由铵来表征，通过对地下水硬度升高原因的分析，论述了人类活动影响地下水水质演化的基本机理。 |

| Impacts of Human Activities on the Evolution of Groundwater Quality in Hebei Plain |

| Abstract:Human activities have changed the natural evolution of groundwater in Hebei Plain. Groundwater hardness can serve as the integrated index of the quality evolution of groundwater under the impact of human activities. The impacts of human activities on groundwater were studied by analysing the mechanism responsible for the increase of the groundwater hardness. The research also indicates that ammonium is one of the indices for the significant contamination of groundwater. |
