中文摘要:

为了打造生态沣河,本文基于秦渡镇断面2001-2009年的定期水质监测资料,以及秦渡镇水文站2001年到2009年的逐日流量数据,以及2009年到2011年大峪口断面、秦渡镇断面的多场洪水监测资料,研究分析了沣河水质与流量之间的关系。结果表明:(1)监测断面流量的大小和每场洪水平均流量的大小均对NH₃-N、TN和COD的污染浓度有影响,且流域上下游不同断面的水质流量之间的关系也有差异；(2)根据2002年到2008年秦渡镇断面所监测的6场洪水资料,可知洪水对COD非点源污染的影响较大。而2006年NH₃-N、TN的点源污染严重,此外几年NH₃-N的点源污染较严重,TN变化不稳定。

英文摘要:

In order to build ecological Feng River,the paper explores and analyzes the relationships between the water quality and water flow on the basis of the regular water quailty monitoring data in Qinduzhen section from 2001to 2009,and the daily flow data in Qinduzhen hydrological station from 2001to 2009,and the flood monitoring data in Dayukou section and Qinduzhen section from 2009to 2011.The results show that the concentrations of NH₃-N,TN and COD are affected by the size of the monitoring sectional flow and the average flow of every flood.In addition,there are differences in the relationships between the different sections of upstream and downstream in the river basin; According to the flood monitoring data of Qinduzhen section from 2002to 2008, we can see that the impact of flood on the non-point source pollution of COD is greater. The point source pollution of NH₃-N and TN is prominent in 2006, and in other years, the point source pollution of NH₃-N is serious and the change of TN is not stable.
