摘要

The water quality of the Tianzhuang Reservoir and its inflows were assessed with the single factor index method to identify the main pollution factor of the reservoir. The spatial-temporal distribution of nitrogen were analyzed to gross judge the main pollution sources. The results indicate (NO_3)~--N accounts for more than 65% of the TN in the Tianzhuang Reservoir. The water quality cannot meet V grade of the Environmental Quality Standards for surface Water for NH3-N and TN exceeding the respective standard. The (NO_3)~--N concentration of the reservoir equals to that of the inflows which affect by non-point source pollution (NPS) from agricultural areas. Therefore NPS is the main pollution source for (NO_3)~--N of the reservoir. In addition, the bottom sediments are the important pollution source for NH_3-N. The results can aid in identifying the key pollutants and their sources of the reservoir.
