地下水的ＥｈＷ值是反映其氧化还原能力的水文地球化学参数，是确定铀氧化还原环境必不可少的参数之一。在准噶尔盆地东部进行１∶５０万层间氧化带砂岩型铀矿床区调时，受工作条件限制，没能对所采集到的水样进行ＥｈＷ值测定，因而影响了对水的氧化还原能力的评价，但是这批水样分析资料中的Ｆｅ２＋／Ｆｅ３＋是非常有用的氧化还原电对，可用来模拟计算地下水环境的ＥｈＷ值。详细讨论了应用地球化学模式来模拟计算地下水ＥｈＷ值的原理和结果。
The EhW value of groundwater is a hydrogeochemical parameter that reflects its redox potential and is one of the indispensable parameters for determining uranium redox environment. In the case of 1: 500,000 zone of interlayer oxidation zone sandstone-type uranium deposit in the eastern part of Junggar Basin, the EhW values of the collected water samples were not measured under the working conditions, thus affecting the water redox capacity However, Fe2 + / Fe3 + in these water samples is a very useful redox couple that can be used to simulate the EhW values of the groundwater environment. The principles and the results of simulating groundwater EhW values using geochemical models are discussed in detail.
