| 摘 要： | 近几年来,河池市地下水总硬度出现逐年升高趋势。本文采用地下水化学成分随机抽样回归分析法分析其形成机理。认为该市地下水总硬度的组成是以重碳酸盐和硫酸盐为主,而硬度的升高是以组成暂时的重碳酸盐的增大表现出来的。并对防止地下水硬度升高提出具体意见。

| Abstract: | There has been a tendency of yearly increase in the total hardness of the underground water in Hechi City, Guangxi. The chemical compositions of the uderground water and the results of regression analysis of the data obtained show that the compositions responsible for the hardness of the underground water are dominated by HCO3- and SO42-, and that the yearly increase in the hardness is due to a yearly increase in the concetration of HCO3- in the underground water. This paper also suggests soms measures to be taken to prevent the increase in the hardness of the underground water. |
