摘要以梁滩河为研究对象,从上游到下游布置了15个采样点,研究了这些采样点的氮、磷浓度,并以其中几个采样点为主
要对象,着重研究了氮、磷在不同深度的垂直分布情况。结果表明,梁滩河的上游左支氮、磷浓度已经较高,而上游右支受污染严重,
特别是 TN 严重超标,说明长期受到生活污水和农业废水的污染。分析其垂直分布规律,TN、TP 最高值大多出现在中间层,TP 在
底层的浓度总体要比表层高,而 TN 在底层的浓度总体要比表层低。梁滩河沉积物中氮、磷主要集中在中间层,中间层是营养物储
存的主要场所。

Abstract: 15sampling sites were arranged from upstream to downstream of Liangtan River to determine the
concentration of TN and TP in the sediments of Liangtan vertical distribution of nitrogen and phosphorus
in sediment of 5-6target sampling sites was studied showed that the concentration of nitrogen
and phosphorus in the left branch of upper Liangtan River was high;the right branch of upper Liangtan River was se-
riously polluted,especially by findings indicated that the Liangtan River was long-term polluted by
the domestic wastewater and agriculture maximum TP and TN value were both appeared in the mid-
dle concentration of TP in the bot
