兰州市傍河水源地环境同位素和水化学研究

Research on Water Source along the Huanghe River in Lanzhou City by Environmental Isotope and Hydrochemistry

本文研究兰州地区大气降水、黄河水和地下水的环境同位素,以及水化学组分特征,并以此探讨了黄河马滩——崔家大滩傍河水源地开采条件下巨厚砂砾卵石含水层不同含水段之间地下水的垂向水力联系、补给来源、水质恶化原因。

The characteristics of environmental isotopes of meteoric water, Huanghe River water and groundwater and their hydrochemical ingredients in Lanzhou district, are investigated in this paper. Therewith the vertical hydraulic connection, source of recharge, reasons for water quality deterioration among different thick aquifers of sandy gravel and cobble under the condition of exploitation along the wather source by the section of Huanghe River between Matan and Cui Jia Datan are discussed.
