| 摘 要： | 通过估算2007年我国南方溪流九龙江流域库区河段的NH4-N和TP的输送通量，探讨水库对营养盐的滞留效应。该河段径流量和营养盐通量均表现出丰水期高枯水期低的季节性特征。系统对NH4-N存在较强的正滞留效应，滞留率为32％，对总磷的滞留率为-10％，可能是河流“湖库化”导致河流沉积物中磷大量释放。

| Abstract: | Here, we presented the estimated NH4 -N and TP budget in the Jiulongjiang Reservoir Reach in 2007 to find out the effect of nutrition retention. The results reveal that the amount of runoff and the nutrient flux were both high in the wet season and low in the dry season. The NH4 -N was highly retained at a rate of 32%. While the TP retention rate was - 10% , it is possibly because a large amount of TP was released from the sediments when the river was turned into a reservoir. |
