【摘要】：氟是人體的必須元素之一,飲水中氟元素過量會導(dǎo)致地氟病。高氟地下水的形成機制一直是水文地球化學(xué)研究的一個熱門話題。利用在張掖盆地開展1∶5萬水文地質(zhì)調(diào)查所獲得的大量水位、水質(zhì)資料,運用水化學(xué)和氘氧同位素方法,在較高精度水平上探討了龍首山前高氟地下水的形成機制。研究結(jié)果表明,龍首山前地下水中的F-主要來源于龍首山含氟巖石,通過季節(jié)性洪水的方式補給到盆地的第四系含水層中,并與盆地上游來源的低氟地下水發(fā)生混合,使龍首山前地下水分為三個條帶。
[Abstract]:Fluorine is one of the essential elements in human body. Excessive fluoride in drinking water can lead to endemic fluorosis. The formation mechanism of high fluorine groundwater has been a hot topic in hydrogeochemistry research. Based on the data of water level and water quality obtained from the 1: 50 000 hydrogeological survey in Zhangye Basin, the formation mechanism of high fluorine groundwater in the Longshoushan Mountains was discussed on the basis of hydrochemistry and deuterium oxygen isotope method. The results show that the F- in the groundwater in front of Longshou Mountain is mainly derived from fluorine-bearing rocks in the Longshoushan Mountains. It is recharged to the Quaternary aquifer of the basin by seasonal flood and mixed with the low-fluorine groundwater from the upper reaches of the basin. The groundwater in front of Longshou Mountain is divided into three bands.
