| 摘要: |
| 水盐运移特征的变化及其对盐碱土的影响是大规模盐碱地改良工程实施时需要考虑的主要问题。由于河套灌区是我国重要的商品粮产区，土壤盐渍化是影响灌区高质量发展的关键因素，水盐的均衡计算分析也逐渐成为灌区盐碱地治理过程中水盐运移研究的重要内容。本文以五原县5万亩“改盐增草(饲)兴牧”试验示范项目区为研究区，采用区域土壤-地下水-地表水信息定点监测方法，利用数字农业云平台获取监测数据，以年灌排时段为周期，讨论了灌水量、降雨量；土壤的深层渗漏量；土壤的地下水补给量；土壤蒸发量；明沟排水量6个方面的因素对区域水盐运移的影响，完成了河套灌区盐碱地改良条件下水盐均衡计算。定量分析表明，研究区改良期内控盐效果和排盐效率逐年提高，根系层土壤由积盐转脱盐，水土环境逐年改善。 |

| Abstract: |
| Changes in the characteristics of water and salt migration and their impact on saline-alkali soils are the main issues that need to be considered during the implementation of large-scale saline-alkali soil improvement projects. As the Hetao irrigation area is an important commercial grain production area in my country, soil salinization is a key factor affecting the high-quality development of the irrigation area. The calculation and analysis of water and salt balance has gradually become an important content of the study of water and salt transport in the process of saline-alkali land management in the irrigation area.In this paper, the 50,000 mu "salt, increase grass (forage) and grazing" experimental demonstration project area in Wuyuan County is used as the research area, and the regional soil-groundwater-surface water information fixed-point monitoring method is adopted, and the digital agricultural cloud platform is used to obtain monitoring data.The annual irrigation and drainage period is a cycle, discussing the impact of irrigation water and rainfall; deep soil leakage; soil groundwater replenishment; soil evaporation; open ditch drainage on regional water and salt transport. Calculation of water and salt balance under the condition of improving saline-alkali land in Hetao Irrigation District.Quantitative analysis showed that during the improvement period of the study area, the salt control effect and salt discharge efficiency increased year by year, the root layer soil changed from salt accumulation to desalination, and the water and soil environment improved year by year. |
