摘要In situ monitoring of water and salt transport in saline soil is a valuable tool for the rational exploitation and conservation of water and soil resources in coastal areas. In this paper, an automatic monitoring device was used to monitor the vertical variation of soil resistivity during leaching in laboratory and field experiments. The experimental results showed that the resistivity peak moved downwards and eventually disappeared during leaching. An equation describing the change in leaching speed over time was obtained. It was found that the desalination occurred from top to bottom and that the desalination depth was constant when the same volume of leaching fluid was applied. Resistivity indication and salinity content showed a significant exponential correlation (R (2) > 0.9). The field experiment demonstrated the stability of data transmission, and variations in apparent resistivity in one day and over a longer period were observed. Rainfall resulted in the downward migration of salt from surface soil, whereas evaporation led to migration of salt upward. The temporal and spatial resolution of this monitoring device can be adjusted to achieve dynamic monitoring, providing an easy means to manage soil and water conservation.
