中文摘要	为揭示干旱区农田沟灌模式下田间尺度土壤水盐运移规律,选定甘肃省景泰川电力提灌灌区为研究区,通过构建HYDRUS-3D沟灌田间水盐运移三维模型,对一个灌水周期内田间微观尺度的土壤水盐运移过程进行了模拟与验证分析。结果表明:运用田间试验实测值对HYDRUS-3D模型中的参数及边界条件修正之后,模拟结果合理,模型可靠性较高;在一个灌水周期内,模拟试验区内的土壤平均含水率呈逐渐减少的趋势并在灌水结束约20天后达到稳定值20%,且沿纵向分层现象明显;在灌溉水淋洗与水分蒸散发耦合作用下,模拟区土壤含盐量呈现先下降后上升的趋势,整个沟灌模拟区域内的含盐量出现了明显的分区现象,表现为沟顶种植一侧(7 mg/cm~3)>中间部分(3.8 mg/cm~3)>灌水沟一侧(2.5 mg/cm~3)。研究结果可为干旱区土壤盐碱化治理提供参考。
英文摘要	In order to reveal the soil water and salt transport pattern at the field scale under the furrow irrigation mode in the arid zone, a HYDRUS-3D model was constructed to simulate and verify the soil water and salt transport process at the microscopic scale in one irrigation cycle. The results showed that the simulation results were reasonable, and the model was reliable after the parameters and boundary conditions in the HYDRUS-3D model were corrected with the measured values from field experiments. The soil moisture in the simulated test area gradually decreased during one irrigation cycle and reached a stable value of 16% about 20 days after the end of irrigation, and there was a significant stratification phenomenon along the longitudinal direction. Under the coupling effect of irrigation water rinsing and water evapotranspiration, the soil salinity in the simulated area showed a trend of first decreasing and then increasing, and the salinity in the whole simulated area of furrow irrigation showed an obvious zoning phenomenon, which showed that the planting side at the top of the furrow (7mg/cm~3) > the middle part (3.8mg/cm~3) > the irrigation furrow side (2.5mg/cm~3). The results of the study can provide reference for the management of soil salinization in arid areas.
