摘要
青弋江流域宣芜段为皖江经济带重要组成部分,了解该地区的地表水和地下水的补径排关系,可以为后续水资源的合理开发利用提供基础资料和理论依据。该文通过分析56组地下水样和7组地表水样的氢氧稳定同位素特征,发现地表水和地下水最终来源于降水补给。泉水在出露地表之前,与围岩发生了同位素交换作用。井水普遍受到一定程度的蒸发作用,导致井水氢氧稳定同位素发生一定程度的分馏。水库水受蒸发效应影响显著。地表河水显示出混合效应。
Xuanwu section of Qingyi River Basin is an important part of the Wanjiang Economic Belt.Understanding the relationship between surface water and groundwater in this area can provide basic data and theoretical basis for the subsequent rational development and utilization of water resources.By analyzing the characteristics of the stable hydrogen and oxygen isotopes of 56 groups of groundwater samples and 7 groups of surface water samples,it is found that surface water and groundwater ultimately come from precipitation recharge.The spring water had an isotope exchange with the surrounding rock before it was exposed to the surface.Well water is generally subject to a certain degree of evaporation,which leads to a certain degree of fractionation of the stable isotopes of hydrogen and oxygen in the well water.Reservoir water is significantly affected by the evaporation effect.River water show a mixed effect.
