| 摘 要： | 以二百方子湿地为对象,模拟研究了沼泽湿地硝态氮和铵态氮在一定水位条件下的垂直运移过程。结果表明:沼泽湿地土壤中硝态氮的穿透曲线具有不对称的多峰结构,而铵态氮的穿透曲线均具有偏峰型结构,且有明显的拖尾现象;各层土壤中硝态氮和铵态氮的穿透曲线最高峰出现的时间及其峰值高低均存在显著差异。 |
| 关 键 词： | 沼泽湿地 硝态氮 铵态氮 穿透曲线 垂直运移 |

| 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. |
| Keywords: | wetland nitrate nitrogen ammonia nitrogen penetration curve vertical movement |
