珲春盆地地下水化学特征与环境质量评价

Chemical properties of underground water in Hunchun basin and evaluation on its environmental quality

以大量水质监测资料为基础,利用统计方法总结了珲春盆地地下水化学特征及其分布规律,进行了地下水环境质量评价,划分了水质级别及其分区,并绘制了相应的分析图件,确定了自然因素(Fe、Mn)和人为因素造成的NH4-N、NO3-N和NO2-N为主要污染组分,提出了地下水开发利用与保护的建议。

Based on a great number of water quality monitoring data,the paper sums up with statistical method the chemical properties and distribution law of groundwater in Hunchun basin,evaluates quality of groundwater environment,classifies water quality and its distribution area,and develops corresponding analysis drawing.Moreover,the paper holds that the natural Fe,Mn and artificial NH4-N?NO3-N and NO2-N are the main factors resulting in pollution,and gives propositions for groundwater development and protection.
