摘　　要：针对沈抚地区用水安全问题,对新宾县新宾镇进行地下水取样测试,测试结果分析表明,新宾镇地下水Mn,NH_4^+,NO-2,K+,TFe,Al,PO3-4,NO-3等指标变异系数超过1,Mn,NH_4^+变异系数超过3,为强分异,表明其空间变化较大。新宾地下水水化学类型以HCO_3-Ca为主,其次为HCO_3-Ca+Mg型。从地下水质量分析,地下水的超标组分为NO-3,Al,TFe,Mn。根据因子分析认为,岩石溶滤作用与与农业活动是影响区内水化学形成的主要因素。In accordance with the safety of water consumption of Shenfu District,a sampling test on the groundwater in both Xinbin Manchu Autonomous County and Xinbin Town has been carried out.The test items consist of Na^+,K^+,Ca^+,Mg^+,Cl^-,SO4^2-,HCO3^-,NH4^+,NO2^-,NO2^-,PO4^3-,total hardness,pH,COD,total dissolved solids,Mn and TFe.According to the results,it is found that coefficients of variation for items including Mn,NH4^+,NO2^-K+,TFe,Al,PO4^3-and NO2^-in the groundwater of Xinbin Town are more than 1 while that for both Mn and NH4^+.In other words,it indicates that they range in large spatial variation with strong differences.Moreover,piper results show that the primary hydrochemistry type of groundwater in Xinbin Town is HCO^3-Ca then the HCO3-Ca+Mg.Based on an analysis on the groundwater quality,it can be concluded that contents over standard are NO2^-,Al,TFe and Mn.Furthermore,both lixiviation of rocks and different agricultural activities are thought as the main factors that lead to hydrochemistry in this District on the basis of factors analysis.
