摘要
利用土壤水中稳定同位素随深度变化的基本规律,对黑河流域不同地下水埋深条件下的地下水蒸发量进行了量化研究,建立了黑河流域地下水蒸发量与地下水位埋深之间的关系曲线。通过实际应用,基于同位素技术的地下水蒸发量计算是量化地下水蒸发量的一种有效方法,获取的地下水蒸发量与地下水埋深关系曲线可对黑河流域地下水资源均衡计算、地下水数值模拟(潜水蒸发模块)等提供有力的数据支撑和参考。
Based on the principle of isotopic content change with depth in soil water,the research on quantification of groundwater evaporation with different depths to groundwater is carried out in the Heihe River Basin.The relationship between groundwater evaporation and depth to groundwater in the Heihe River Basin is established.Through the practical application,it shows that the groundwater evaporation calculation method based on the isotopic technique is very useful to quantifying the groundwater evaporation.The obtained relation curve between groundwater evaporation and depth to groundwater can provide data support and reference for groundwater resources assessment and groundwater numeric simulation.
