| 摘 要： | 以付老文泡湿地和二百方子湿地为研究对象,对比研究了封闭性湿地和开放性湿地土壤中铵态氮含量的季节动态变化特征,结果表明,两类湿地土壤铵态氮含量的季节动态变化较为一致,受湿地水文条件的影响较弱;各层土壤铵态氮含量基本上都呈不规则的“M”形的双峰曲线变化,其季节动态过程均可采用高斯多峰拟合来模拟其动态变化,且模拟效果都较理想。 |
| 关 键 词： | 湿地 土壤 铵态氮 季节动态 |

| Abstract: | Fulaowenpao and Erbaifangzi were chosen in this study to determine the seasonal dynamic characteristics of ammonium nitrogen concentrations in soils from both closed and open wetlands.The results for the dynamic changes in ammonium nitrogen concentrations in soils for the two types of wetlands were shown to be consistent,and were shown to be influenced on a weekly cycle by wetland hydrology.At the two sites used in the study,the changing tendency of ammonium nitrogen concentrations in each layer of soil appeared in an anomalous "M" shape.This suggested that the characteristics of seasonal dynamics of ammonium nitrogen concentrations in soils from the closed wetland were similar to those of the open wetland.The changing processes of ammonium nitrogen concentrations in soils from each of the soil layers can be represented with a third-order polynomial. |
| Keywords: | wetlands soils ammonium nitrogen seasonal dynamic |
