新疆罗布泊罗北凹地地下卤水化学场特征研究

Study on Chemical Field Characteristics of Underground Brine in North Depression Area of Luobupo in Xinjiang Uygur Autonomous Region

摘要:

简要介绍了新疆罗布泊罗北凹地地下卤水的水化学场特征，包括研究区地下卤水主要水化学类型为硫酸镁亚型和地下卤水宏量组分的水平和垂直分带性。另外，通过水样同位素测定分析研究了该区地下卤水的形成机制，即罗布泊古湖水主要由塔里木河等地表水及大气降水补给，后经过强烈的蒸发浓缩作用而形成的。

Abstract:

In this paper, chemical field characteristics of underground brine in northern depreesion of Luobupo in Xinjiang Uygur Autonomous Region has been briefly introduced. Major chemical type of the underground brine is magnesium sulfate sub-type, horizontal and vertical zonation of macro ingredient of underground brine has been introduced, and water sample determination has been carried out. Through study on the forming mechanism of underground brine in this area, it is regarded that Luobupo lake is mainly replenished by surface water of Tarim river and precipitation, and condensed by stronger evaporation.
