根据于田绿洲地下水水质分析的结果,运用回归分析方法分析地下水化学特征,得出如下结论:依据布罗德斯基分类法,提出了研究区共存在Cl·HCO3-Na·Mg、HCO3·Cl-Na·Mg、Cl·HCO3-Mg·Na等共8种化学类型的地下水;HCO3-和Cl-与可溶性总盐的相关关系显著,且回归方程拟合效果均理想,而CO32-和SO42-与可溶性总盐的相关关系均不明显;(Na++K+)和Mg2+与可溶性总盐的相关关系显著,且回归方程拟合效果理想,而Ca2+与可溶性总盐的相关关系不明显。
According to the results of the groundwater quality analysis in Yutian Oasis and using the regression analysis method to analyze the chemical characteristics of the groundwater, the following conclusions are drawn: According to the Brodnski classification method, it is proposed that co-existence of Cl · HCO3-Na · Mg, HCO3 · Cl -Na · Mg, Cl · HCO3-Mg · Na and so on. There was a significant correlation between HCO3- and Cl- and total soluble salts, and the regression equation fitting results were satisfactory. However, CO32- and SO42- And soluble total salt were not significant. The correlation between (Na ++ K +) and Mg2 + and soluble total salt was significant, and the regression equation fitting effect was satisfactory, but the correlation between Ca2 + and total soluble salt was not obvious.
