摘要
对石家庄市 1991~ 1997年间的浅层地下水环境质量进行了分析评价 ,查明了地下水环境的演化趋势。用绝对值关联分析和 Q型因子分析等方法得出了地下水中具有代表性的化学指标和具有代表性的水样。在此基础上 ,运用等维灰数递补技术预测了地下水总硬度的变化趋势。最后 ,分析了人类活动对地下水环境质量演化的影响 ,并提出缓解建议。
Based on the monitoring data during 1991—1997,the groundwater environmental quality in Shijiazhuang was analyzed and assessed, and the evolution trend of the groundwater environment was studied. The representative chemical index and the typical sampling site were chosen by means of absolute value\|correltion analysis and Q factor analysis, respectively. On the basis of aforementioned works, GM(1,1)model was employed to predict the total hardness change of groundwater in later years. Finally, the impacts of human activities on the evolution of groundwater affected was briefly discussed, and the proposals to control the groundwater environment quality were put forward.
