摘　　要：平阴县浅层地下水调查采样密度为1点/16km2,分析测试27项指标的含量变化规律后,认为调查区浅层地下水中除K,Mn,NO2-等指标含量变化较大,局部富集外,其他指标含量变化小,在浅层地下水中分布较均匀。选择As,Ba,Be,Cd,Co,Cu,Fe,Hg,Mn,Mo,Ni,Pb,Se,Zn,F-,Cl-,Cr6+,NO-2,COD,pH等20项指标,按《地下水质量标准》对浅层地下水环境质量进行的单因子和综合评价,结果显示较好级以上者达88.4%,而较差级仅占11.6%,无极差级分布,调查区内浅层地下水环境质量状况良好。The sampling density of shallow underground water is 1 spot in 16km^2 in Pingyin county. After the analysis on content variation rule of 27 indicators, it is regarded that the content variation of some indications are great and rich concentrated, such as K, Mn and NO2^-, and the content variation of other indicators are small in the underground water in investigation area. According to the ＂evaluation of underground water quality standard＂, single indicator and comprehensive evaluation of environmental quality of shallow groundwater are carried out. It showed that the better and above level water quality are 88.4%, the lower level is 11.6%, and non - distribution of very poor level. The environemnt quality of shallow groundwater is in good condition.
