Description:
The study analyzed dynamic characteristic of nitrogen and phosphorus and influencing variables in three representative input tributaries of Miyun Reservoir from 2012 to 2016. The results showed that Chaohe River in the study period had relatively high TN, NO 3 - -N and NH 4 + -N concentrations. While high phosphorus content was found in Qinghe River. Basing on environmental quality standard for surface water, NO 3 - -N, NH + -N and TP met the drinking water criterion in most samples. However, TN content met the drinking water criterion only in less than 15% samples. In Qingshuihe River, pH and TSS were significantly variable due to nitrogen variations and TOC was significantly variable for phosphorus variations. However, water parameters (BOD, COD, TSS, TOC, EC and pH) had no significant effects on nitrogen and phosphorus dynamics in Chaohe River and Baihe River.
