- 摘要:
- 为揭示镇江市古运河河岸带表层沉积物中氮元素含量的分布特征，结合古运河周边环境状况，选择6个典型的采样点对其表层沉积物进行样品采集，对各样品沉积物总氮（TN），氨氮（NH4+-N），硝氮（NO3--N），亚硝氮（NO2--N）以及有机质（O.M）和pH值进行了分析，并根据经验公式对沉积物有机氮进行了计算。结果表明，TN，NH4+-N，NO3--N，NO2--N以及Org-N含量介于0.39~2.40 g/kg，1.63~11.31 mg/kg，2.46~6.95 mg/kg，0.54~2.29 mg/kg，0.99~2.32 g/kg，总氮和有机氮的变异系数最大，为83.59%，氨态氮、硝态氮以及亚硝态氮的变异系数介于40.36%~49.15%，表现为中等离散程度，表明研究区域总氮和有机氮的离散程度较高，其在空间分布上呈现较为明显的异质性；古运河沉积物有机质含量介于0.99%~2.32%，变异系数为32.50%，表现为中等变异性，表明各采样点的沉积物有机质含量变化幅度中等；通过沉积物C/N值来判断，古运河有机质主要以陆源贡献为主；相关性分析结果表明，NO2--N与TN的关系最为密切，而氨氮与硝氮、亚硝氮以及有机氮之间的相关性不强，说明氨氮与其他形态氮在沉积物方式上存在一定的差异性。此外，pH值对古运河表层沉积物氮形态的具有较为显著的影响。
- Abstract:
- In order to reveal distribution characteristics of nitrogen and organic matter in riverside surface sediments of the Ancient Canal in Zhenjiang, we selected six sampling sites in the riverside of Ancient Canal, and took the sediment samples from the sites. Total nitrogen (TN), ammonia nitrogen (NH4+-N), nitrate nitrogen (NO3--N), nitrite nitrogen (NO2--N) and organic matter (OM) of the samples were measured, and organic nitrogen (Org-N) was calculated according to the empirical formula. The results showed that the contents of TN,NH4+-N,NO3--N,NO2--N and Org-N ranged from 0.39 to 2.40 g/kg, from 1.63 to 11.31 mg/kg, from 2.46 to 6.95 mg/kg, from 0.54 to 2.29 mg/kg, and from 0.99 to 2.32 g/kg. The coefficient of variation (C. V) was highest for TN and Org-N (83.59%), followed by NH4+-N, NO3--N and NO2--N (40.36%~49.15%), indicating that the TN and Org-N obviously varied among the sampling sites. The content of organic matter ranged from 0.99% to 2.32% and its coefficient of variation was 32.50%, indicating that the content of organic matter moderately varied among the sampling sites. According to the C/N values, the source of organic matter in the Ancient Canal of Zhenjiang is mainly dominated by the terrigenous pollutants. Correlation analysis results show that there is the closest relation between NO2--N and TN, whereas the correlation relation between NH4+-N and NO3--N, NO2--N, Org-N were not significant, indicating that the there were certain differences of ammonia nitrogen and other forms of nitrogen in the sediment. In addition, the pH value of the ancient canal had very significant effect on the forms of surface sediment nitrogen.
