飞来峡水库氮磷营养盐形态及分布特征
Forms and distribution of nitrogen and phosphorus in Feilaixia Reservoir
摘要
Abstract
Samples collected from 9 sites in the Feilaixia Reservoir in June and December of 2015 are used to analyze the forms and distribution of nitrogen and phosphorus by measuring their concentrations and combining Spearman correlation test results and N/P ratio.The results show that:① NO3--N,PP and DP are the main forms.② TN concentrations during wet season are lower than those during dry season,while TP concentrations are higher during the wet season.The nitrogen concentration is mainly influenced by domestic sewage and phosphorus is influenced by non-point source pollution.③ Nitrogen and phosphorus may be originated from the same sources during wet season.④ The TN flux in wet season in the Wengiiang River is 1 128.4 g/s,which is the highest among the three main ri ers in the Feilaixia reservoir.The TN flux of the Beijiang River is 1 036.0 g/s,which is the highest in dry season.TP fluxes of the Beijiang River are the highest,with 85.4 and 70.3 g/s in wet and dry season,respectively.⑤ The ratios of DIN/TP range from 4.0 to 47.1,suggesting that the Feilaixia reservoir is in the state of phosphorus limitation.关键词
