3) the first reactor solution is entered in the form of rain making and is seeped into the earth pillar, entered with simulated precipitation ponding
Impregnation rises the supply soil water by hollow billet, until described with second of reactor solution simulated groundwater system to the soil water
The soil water in earth pillar reaches saturation state, is then allowed to stand in near-nature forest state；
4) make the earth pillar fully charge, form frozen soil；
5) earth pillar is heated, frozen soil melting process is simulated；
6) the third reactor solution is entered equally in the form of rain making and is seeped into the earth pillar, and in the earth pillar
Different height and collected downhole water sample；
7) by the content and type of tracer in measurement acquisition water sample, the source of soil moisture is parsed.
Preferably, soil morphology of the earth pillar as a kind of near-nature forest state.
Preferably, tracer used is not adsorbed by soil particle.
Beneficial effects of the present invention are：The present invention infiltrates supply by simulated precipitation and underground water hollow billet rises supply soil
The process of water parses frozen soil soil water moisture source type.Also, the present invention is pushed away by the content of tracer in measurement water sample
Export the source type of the frozen soil soil water.
