Though it is di? Cult to grow trees in the saline-alkali soil, the ground cover and wetland vegetation are rich and vary in response to subtle changes in the water table and PH values.
尽管难以在盐碱地里栽种树木，但覆盖地表和湿地的植被异常丰富，随着地下水位和PH值的细微变化而呈现不同的形态。
The ground water resource in the leaky aquifer is evaluated by the Galerkin s finite element method on condition that the water table of the above recharge aquifer changes with pumping.
越流含水层系统在我国分布十分广泛，但国内有关越流含水层系统的地下水污染模型尚未见报导。
