| Abstract: |
| The Er Bai Fang Zi wetland was chosen as the research target in simulating the vertical movement of nitrate nitrogen and ammonia nitrogen in wetlands at a certain water table. The results revealed that the penetration curve of nitrate nitrogen in wetland soils had an asymmetric multi-peak structure while the penetration curve of ammonia nitrogen had a structure its peak inclining toward one side and its tails protracting; the peaks and peak times and peak values of the penetration curves of nitrate nitrogen and ammonia nitrogen significantly differed among different soil layers. |
