水平衡模型在地下水-地表水相互作用研究中的应用

Application of Water Balance Model in Groundwater-Surface Water Interaction

为更好地了解水平衡模型的应用,笔者分析了水平衡模型的原理,利用河流段流量、地下水流量、溶质浓度和同位素比率的测量值,研究地下水-地表水相互作用。通过选取某河流段作为研究区域,对河流段的流入量、流出量、溶质浓度和同位素比率进行了测量,并采用水平衡模型对模型流入量、模型流出量和模型净平衡进行了分析。结果表明,研究的河流段存在失水情况,通过质量和溶质平衡法可量化模型中的失水率。水平衡模型可作为水资源评价的工具,通过确定河流失水机制来增强水资源的有效利用。

In order to better understand the application of water balance model, the author analyzes the principle of water balance model and studies the groundwater-surface water interaction by using the measured values of river flow, groundwater flow, solute concentration and isotope ratio. By selecting a river section as the research area, the inflow, outflow, solute concentration and isotope ratio of the river section are measured, and the model inflow, model outflow and model net balance are analyzed by using the water balance model. The results show that there is water loss in the studied river section, and the water loss rate in the model can be quantified by mass and solute balance method. Water balance model can be used as a tool for water resources evaluation to enhance the effective utilization of water resources by determining the mechanism of river water loss.
