| 摘 要： | 以四川省龙泉湖湖泊表层沉积物和表层水体为研究对象,分析了表层沉积物的各种水溶性氮含量和表层水体的硝态氮和氨氮的含量。结果表明,表层沉积物中水溶性总氮、水溶性氨氮和水溶性硝态氮的平均含量分别为6.64,1.22和2.83mg/kg,水体中硝态氮和氨氮的平均含量分别为5.09和0.05mg/L;表层水体和表层沉积物中的硝态氮含量无显著相关关系,但表层水体和表层沉积物中的氨氮含量呈显著正相关,说明表层水体中氨氮可能是由沉积物释放而来。

| Abstract: | Different forms of water soluble nitrogen contents in surface sediment and contents of NO3-N and NH3-N in surface water from Longquan Lake, Sichuan Province were studied. Average contents of water soluble total nitrogen, water soluble NH3-N and water soluble NO3-N were 6.64 mg/kg, 1.22 mg/kg and 2.83 mg/kg in surface sediment, respectively. Average contents of NO3-N and NH3-N were 5.09 mg/L and 0.05 mg/L in surface water, respectively. The correlation of NO3-N content between surface water and surface sediment was not significant, but NH3-N content between surface water and surface sediment was significantly positively correlated, indicating that NH3-N of surface water may be caused by NH3-N released from surface sediment. |
