黄河农场地区地下水入海通量的数值分析

在系统地调查和分析了黄河三角洲地区自然地理、地质和水文地质条件的基础上，进行了不同的水文地质试验和地下水长期观测，并尝试建立黄河三角洲典型地段－黄河农场地区的水文地质数学模型，定量分析该地区地下水入海量的变化规律及不同因素的影响程度。研究结果表明，当地的气象因素和黄河、小岛河及海洋的水位都不同程度地影响地下水的入海量，而且黄河的水位变化和气象因素是影响黄河三角洲地区地下水入海量的主要因素。另外，黄河三角洲地区地下水的入海量比地表径流入海量小得多。

Numerical Analysis of Groundwater Discharge Fluxes to Ocean From the Huanghe Farm Area

On the basis of investigation and analysis of natural geographic, geologic and hydrogeologic conditions in the Yellow River delta, different in door tests and long term observations for groundwater level have been carried out. Further, a hydrogeologic model is set up for the Huanghe Farm area to calculate the groundwater discharge fluxes and to quantitatively analyze the influence of different factors. The results show that local climate and water levels of the Yellow River, Xiaodao River and the sea, to some degree, affect the groundwater discharge fluxes to ocean, but the water level variety of the Yellow River and the climate are major effective factors. In addition, the groundwater discharge is much smaller than the surface water runoff in the Yellow River delta.
