Measuring soil erosion or deposition using magnetic susceptibility
A measurement method for measuring the thickness of a soil layer based on magnetic susceptibility, related to the technical field of soil erosion monitoring. The method comprises: measuring the original magnetic susceptibility Kb of a surface soil layer of sampling point soil (S1); measuring the maximum magnetic susceptibility Km with a magnetic element placed on the surface soil layer (S2); burying the magnetic element at a preset depth below the sampling point soil to form a magnetic layer (S3); measuring a first magnetic susceptibility K1 of the surface soil layer directly above the magnetic layer (S4); after a preset time interval, measuring a second magnetic susceptibility K2 of the surface soil layer directly above the magnetic layer (S5); and calculating a thickness variation value of the soil layer on the basis of a conversion equation between the magnetic susceptibility of the soil layer and the thickness of the soil layer (S6). The measurement method for measuring the thickness of a soil layer based on magnetic susceptibility has extremely small or no disturbance to a sampling point soil layer, produces a measurement result quickly and accurately, obviates the need for any special manual maintenance, provides a great representation of the sampling point soil layer, and has high practicability in scientific research and field monitoring for soil resource protection and soil erosion monitoring.
