Abstract:: In this study, the contents of carbon, nitrogen, and phosphorus in the sediments of 16 sampling points in the Shaanxi section of the Weihe River from 2014 to 2016 were measured. Based on the analysis of the temporal and spatial characteristics of the contents of carbon, nitrogen and phosphorus in the sediments, the fuzzy comprehensive evaluation method was used to evaluate the pollution of nutrients in the sediments of the Weihe River in Shaanxi. The results showed that the contents of carbon, nitrogen and phosphorus in the sediments decreased in 2016 compared with the previous two years, but there was no significant change during the flood season in 2015; the distributions of the contents of carbon, nitrogen, and phosphorus in the sediments had the similar spatial characteristics, reaching peaks in Qingjiang River and Bahe River, and reaching troughs in Xingping and Shawangdu; the pollution condition of sediment nutrients in the Shaanxi section of the Weihe River was level Ⅱ, and there were certain ecological risks. It is necessary to pay attention to the external input of phosphorus and the management of pollutant treatment and discharge in tributaries.
