摘要: 该文以内蒙古河套灌区为背景展开田间耕荒地水盐运移规律研究。在田间试验基础
上,分析作物生育期耕荒地土壤水盐的运移机理,利用水均衡模型对耕荒地土壤水的迁移规
律及水收支进行了模拟分析。利用盐分收支模型计算耕荒地的盐分累积量。结果表明,作物
生育灌溉期间耕地和盐碱地的水分收支基本是平衡的。定量的确认了耕地的一部分灌溉水量
通过地下水渗透侧向补给邻接盐荒地,被盐荒地蒸发所消耗。此期间耕地和盐荒地都是处于
积盐状态,耕地累积盐分 74g/m2,盐荒地累积盐分 400g/m2。荒地做为灌区盐分的贮存地,
是灌区水盐平衡的重要调节因素,对干旱灌区水盐动态的研究具有重要意义。

In this study water and salt transport were studied in the irrigated field and
uncultivated land of Hetao Irrigation District in Inner Mongolia province. Based on field
experiments, Water and salt transport mechanism of the irrigated field and uncultivated land was

analyzed in the irrigation district. Meanwhile, water and salt transport dynamics and salt
accumulations were simulated with water balance and salt balance model, receptively. Results
show that the input/output of water and salt of field and uncultivated land were b
