| 摘 要： | 丰水期对汇入红枫湖的后六河、麻线河、羊昌河和桃花园河等河水中氮素的形态和含量进行测定,结果表明NO3--N是氮素的主要形态,约占TN的25%~65%;三态氮在空间分布上,从上游至下游,四条河流表现出不同的变化规律,后六河NH4+-N、NO2--N与NO3--N的变化规律基本上一致外,含量总体上逐渐增加;其它三条河流中,NH4+-N与NO3--N的含量呈现相反的变化趋势,NO2--N的变化规律则不明显。该流域整体上表现为非点源污染的特征。后六河和麻线河地下水中NO3--N的含量明显高于相应河水中的含量。该研究对亚热带小流域河水中氮磷含量及形态变化研究具有借鉴意义,对该流域的环境规划、环境管理和环境污染治理具有指导意义。

| Abstract: | This paper measured the chemical species and the concentration of nitrogen in the tributary rivers of the Hongfeng Lake,Houliu River,Maxian River,Yangchang River and Taohuayuan River,during the high water period.The results showed that the NO-3-N is the dominated chemical species,accounts of 25 to 65 percent of the total nitrogen(TN).From the upstream to the downstream of the Houliu River,the TN content increases and the contents of NH+4-N,NO-2-N and NO-3-N are positively correlated.In the case of other thr... |
