| 摘 要： | 以贵阳市鱼梁河龙洞堡段为研究对象,根据河段两岸功能区分布,布设5个监测断面,于枯水期开展水体总氮、总磷短时间尺度(5天一个样品)的同步监测。结果表明,研究区水体受人为活动影响,总氮、总磷含量增加,故应严格控制人为活动,尤其是农业活动产生的磷污染向水体的输入。

| Abstract: | The Longdongbao Section of Yuliang River was selected to monitor the dynamic characteristics of total nitrogen and total phosphorus in river water. According to the distribution of different functional zones along the river bank, five monitoring sections were designed. During dry period, water samples were collected synchronously from these five moni- toring sections with sampling interval of 5 days. The water samples were analysed for total nitrogen and total phosphorus. The results showed that the concentrations of total nitrogen（CTN） and total phosphorus（CTP） in river water were in- creased by human activities. Therefore, phosphorus input to river from human activities, especially the nonpoint source pollution from agriculture, must be strictly controlled. |
