Data of chemical characteristics and reactive transport analysiss of salt ions during freeze and thaw period in Yonglian area

The soil samples were collected in Yonglian experimental station of Hetao Irrigation District, Inner Mongolia Autonomous Region, China, to measure the change of total soil water, soil salt and its ion components. Using these data sets, the FREZCHEM model was used to calculate the soil water and salt content in liquid and solid phases, and then the HYDRUS-1D model was used to simulate the movement of liquid soil water and soluble salt. And the potential migration capability of soil water and salt components were then estimated by comparing the distribution profiles obtained by HYDRUS-1D and FREZCHEM.

本数据集的土壤样品采集于中国内蒙古自治区河套灌区永联试验站，旨在测定土壤总含水量、土壤盐分及其离子组分的动态变化。依托该数据集，研究人员采用FREZCHEM模型计算了固液两相中的土壤水与盐分含量，随后借助HYDRUS-1D模型模拟了液态土壤水与可溶性盐分的运移过程。最终通过对比HYDRUS-1D与FREZCHEM模型输出的分布剖面，估算了土壤水及盐分组分的潜在迁移能力。
