Technical Field

[0001] The utility model relates to the technical field of bottom mud sampling, in particular to a piston-type high-altitude swamp wetland bottom mud stratification sampling device. Background Art

[0002] Alpine swamp wetlands, or alpine swamp meadows, have relatively high soil moisture content, which is basically saturated water content.
