本文以“水量平衡”理论这一调控地下水位的手段,论述了如何解决引黄灌溉突出的泥沙问题和次生盐碱化问题。研究灌区中地下水的水量平衡,查明影响地下水位消涨的因素,从而拟定出调控地下水状况的方法,以便将地下水位保持在适于土地高产稳产要求的深度。
This paper discusses how to solve the salient sediment and secondary salinization problems in the Yellow River Diversion Project based on the regulation of the groundwater level by the theory of “water balance”. To study the water balance of groundwater in the irrigation area and identify the factors that affect the rise and fall of the groundwater level, so as to formulate a method of controlling the groundwater level in order to maintain the groundwater level at a depth suitable for the high and stable yield of the land.
