自然界,冲积平原在垂直剖面上一般都由若干个含水层和弱透水层组合而成,形成较为复杂的含水层系统.对于含水层系统中的含水层水动态与水均衡研究较多.然而,相邻承压含水层的弱透水层水动态与水均衡特征研究的却很少,这主要是因为我们一直以来认为弱透水层是隔水层或相对隔水层,作为水资源量其贡献率很小,因此很少专门给予重视和得到必要的研究,时常将弱透水层忽略或者作为
In nature, the alluvial plain in the vertical section generally consists of a number of aquifers and aquitards combined to form a more complex aquifer system.For the aquifer aquifer water dynamics and water balance more research However, However, there are few studies on the characteristics of water dynamic and water balance in the aquitards of adjacent confined aquifers. This is mainly because we have always considered that the aquitard is the aquitard or the relative aquitard, and its contribution as water resources Very small, so rarely given special attention and get the necessary research, often impermeable to the aquitard or as
