摘要
在全面收集有关黄河三角洲地区水资源方面文献资料的基础上,从含水层、地下水水质、地下水循环和地下水年内动态变化4个方面,详细论述了黄河三角洲地区地下水的基本特征,并将黄河三角洲地区地下水含水层划分为3个大的水文单元,提出了地下水以河道为分水岭呈扇形向海排泄的特征。
After the thorough collection of groundwater samples in the Yellow River delta areas, the groundwater characteristics are discussed in detail in the aspects of aquifers, water quality, water circulation, and annual water dynamic situations. For the first time, the aquifers are divided into three great hydrographic units and the groundwater is considered to discharge into sea in sector shape. Groundwater in the delta is composed of salt water or brackish water, and the relation between charge and discharge is very complex. The dynamic conditions of the groundwater are largely affected by climate and change in evident seasonal character.
