人类活动影响下石家庄市地下水环境质量现状及趋势研究

STUDY ON THE PRESENT SITUATION OF GROUNDWATER ENVIRONMENT QUALITY AND ITS DEVELOPMENT TREND IN SHIJIAZHUANG CITY UNDER THE IMPACTS OF HUMAN ACTIVITIES

对石家庄市１９９１～１９９７年间的浅层地下水环境质量进行分析评价，研究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，并提出了缓解建议。

In this paper, based on the monitoring data during 1991 - 1997, the shallow groundwater environmental quality in Shijiazhuang being analyzed and assessed, and the evolution trend of the groundwater environment was studied as well. The representative chemical index and the typical water sample were obtained by means of absolute value correlative analysis and Q type factor analysis respectively. On this basis, GM(l, l)model was applied to predict the variation trend of total hardness of groundwater, Finally, the impacts of human activities on the evolution of groundwater environmental quality are analyzed, and mitigation recommendations are proposed.
