摘要
利用逐步回归分析法分析了和田子项目区地下水中电导率、总硬度、总碱度、矿化度相互之间及与其它离子的关系,通过点绘各因素两两之间的关系图进行人工分析,以对逐步回归分析法的结果进行修正,使其更符合客观实际,从而得到一种快速确定以上四种指标的方法。分析结果表明:子项目区地下水中总硬度与Mg2+关系良好,矿化度、K+&Na+、电导率、Cl-之间存在相当好的线性关系。并对地下水开发利用和土壤治理对策提出了建议。
The relationships among the indices including conductivity, total hardness,total alkalinity, mineralization degree and ions existing in the groundwater of Hotian sub-project area are analyzed by means of the stepwise regression method and then manual analysises are performed by plotting the relation graphs among the indices to modify the results derived by the stepwise regression method so as to make it more practical. A method is acquired by which the four indices mentioned above can be determined quickly. The analysis results indicate that there is a good relation between total hardness and Mg^(2+), and perfect linear relations exist among total salinity, K^(+)& Na^+, conductivity and Cl^- in the groundwater of Hotian sub-project area. Some advices for the exploitation of groundwater and the improvement of soil are put forward.
