| 摘 要： | 通过对2008年12月份在曹妃甸地区采集测试的25组水化学资料进行分析,探讨了该区地下水的水化学特征,并利用R型因子分析法对影响该区地下水化学组分的4个主要因素进行了研究,结果表明:区内浅层地下水基本都为高矿化的Cl-Na型,深层地下水水化学类型具有一定的水平分带性;高矿化的地表水和潜水主要是蒸发浓缩作用和沿海土壤易溶盐含量高共同影响的结果,深层地下水水化学组分主要受含水介质中易溶盐分组成和补给水高碳酸含量的影响;地下水中NH4+、NO3-和NO2-的广泛检出反映了农业生产和人们生活排污等人类活动对地下水化学组分的影响。 |

| Abstract: | The hydrochemical characters of groundwater were analyzed based on 28 samples taken from Caofeidian area in December,2008.Meanwhile,the R-mode factor analysis method was utilized to recognize the four factors affecting groundwater quality seriously.The shallow groundwater is characterized by high salinity and a chemical type of Cl-Na,and the deep groundwater is characterized by a horizontal zoning.The shallow groundwater with high salinity is mainly influenced by the evaporation and medium with high soluble... |
