摘　　要：根据内蒙古孪井滩灌区的自然地理、地质和水文地质条件，在室内外模拟试验的基础上，利用VS2DT模型对灌溉入渗水的运移进行了模拟，计算了现有灌溉量下的渗漏量，提出了灌区春小麦和夏玉米的节水灌溉模式。春小麦第一次灌溉的节水灌溉量为150mm，第二次灌水的节水灌溉量为97．5mm。以后4次灌水的灌溉量在60～75mm之间。夏玉米第一次灌水的灌溉量也以150mm为宜，以后5次灌溉量分别以127．5mm，90．0mm，97．5mm，82．5mm及67．5mm为宜。此灌溉模式不仅能够节约水资源，而且能够防止土壤次生盐渍化的发展。The simulation of soil moisture movement is carried out using the VS2D/T （Variably Saturated 2- D Flow and Transport Model） model based on the natural hydrographic and geo hydrologic and geologic conditions of the study area and a great many outdoor and indoor experiments. The current irrigation leakage amounts are calculated, and then the water saving irrigation modes of spring wheat and summer corn are presented. The water-saving irrigation amount of the first irrigation is 150 mm in spring wheat field, and that of the second irrigation is 97.5 mm, and the subsequent four irrigations are 60- 75 mm. The first irrigation amount for summer corn had best be confined around 150 mm, and the subsequent five irrigation amounts should be as follows： 127.5 mm, 90.0 mm, 97.5 mm, 82.5 mm and 67.5 mm. Besides saving water resource, the irrigation modes can prevent secondary salinization.
