| 中文摘要: |
| 利用R型因子分析法对宁河地区第四系深层地下水样的水化学数据进行分析,识别出影响地下水化学组成的4个主因子,通过对这4个因子分析研究可知:该地区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NH+4、NO-3和NO-2的广泛检出反映了化肥和农药的广泛施用、城镇生活污水和工业污水的污染等人类活动对地下水化学组分的影响。 |
| 英文摘要: |
| the R-mode factor analysis method is utilized in this paper to analyze the hydrogeochemical data of 20 groundwater samples in Ninghe.Four main factors which affect the quality of groundwater seriously are recognized. From the analysis of the four main factors, we has the conclusion:the deep groundwater is influenced by the soluble salt in aquifers and recharge water with high carbonate, and NH+4, NO-3 , NO2- detected in deep groundwater reflect the impacts of human activities ,such as agricultural production and human sewage from life and industry. |
