【摘要】 [目的]对临沂地区浅层地下水进行质量评价,确定地下水的污染现状。[方法]按每16 km2一个采样点的采样密度采集临沂地区的浅层地下水,共分析35项指标,选取其中影响水环境质量的17项指标进行评价。[结果]临沂地区浅层地下水较差和极差的比例达到了42.69%,影响浅层地下水质量的主要指标为Mn、Pb、Cl-、F-、NO2-、总硬度、溶解性总固体和高锰酸钾指数,多分布在居民聚居区、工矿企业及周边地区。[结论]该研究可为临沂地区地下水水质改良提供基本依据。更多还原

【Abstract】 [Objective]The research aimed to evaluate the quality of shallow ground water in Linyi City,and to determine the situation of ground water pollution.[Method]Shallow ground water were collected every 16 km2in Linyi,and 35 elements or indicators were tested. Among that,17 elements or indicators influencing environment quality were chosen for evaluation in this research.[Result]The results showed that,the worse and the worst ratio reached 42. 69% about shallow ground water quality,the main indicators influencing shallow ground water quality were Mn,Pb, Cl-,F-,NO2-,total hardness and total dissolved solids. They focused on the major areas,industrial and mining enterprises as well as their surroundings.[Conclusion]This research could provide basic references for the improvement of ground water quality in Linyi City.更多还原
