中文摘要	为探明河套灌区典型耕地最佳灌水制度和合理地下水埋深,于2017、2018年连续2年进行了田间试验,选取向日葵农田作为研究对象,应用饱和-非饱和土壤水分及溶质运移理论,利用HYDRUS-2D数值模型对研究区不同灌水量及地下水埋深条件下GSPAC系统中水盐运移规律进行数值模拟,分析了不同灌水量条件下的水盐运移状态.将模拟结果与田间试验实测结果进行对比分析,模型模拟值与实测值较吻合.结果表明,试验区最佳灌水量为82.8~85.5mm,地下水合理调控埋深为160.72cm.研究结果可为干旱区水资源合理利用和水盐调控提供理论依据.
英文摘要	In arid oases irrigation areas, soil secondary salination is one of the main problems leading to land desertification, so as to imperil the soil quality, growing of crops and agricultural production, even leading to abandonment of agricultural soils. Most salinization processes of salt accumulation in irrigated lands are largely determined by the salinity of the irrigation water and the groundwater level in the areas. So it is very crucial to control groundwater and irrigation amount for agricultural development. In order to find out the optimal irrigation amount and reasonable groundwater depth in typical cultivated land in Hetao Irrigation District, field trials were conducted for two consecutive years in 2017 and 2018, and sunflower farmland was selected as the research object, saturated-unsaturated soil moisture and solute motion theory was applied, and HYDRUS-2D numerical model was utilized for numerical simulation of water and salt transport in GSPAC system under different irrigation and groundwater depth conditions in the study area, and analysis of water and salt transport conditions under different irrigation conditions was made to determine the optimal irrigation system and reasonable groundwater depth. The simulation results were compared with the field test results, and the model simulation values were in good agreement with the measured values. The results showed that the optimal irrigation amount in the test area was 82.8~85.5mm, and the reasonable grounding depth of groundwater was 160.72cm. The research can provide a theory basis for rational utilization of water resources and water-salt regulation in arid regions.
