城市水化学特征及影响因素研究——以哈密市为例

Study of Hydrochemical Characterisitics and its Influence Facters in City,Take Hami as an Example

以哈密市第四系松散岩类孔隙水为研究对象,采集了275个样品进行测试分析和处理,利用因子分析法对水质影响因素进行评价.结果表明,该区地下水水质的主要影响因素是:以Na+、Ca2+、Mg2+、Cl-、SO42-、pH值、TDS为主要代表变量的溶滤作用;以总硬度为代表的蒸发作用;以HCO3-为代表的天然背景值的影响.

In this paper,the Quaternary unconsolidated rock pore water in Hami is taken as the research object,and 275 samples are collected,tested,analyzed and treated.By using the factor analysis method to evaluate the water quality factors,results show that the main influencing factors of groundwater quality in this area is the dissolution in Na+,Ca2+,Mg2+,Cl-,SO42-,pH and TDS as the main representative variables,the influence of natural background to total hardness as the representative of the evaporation and HCO3-represents the value of.
