The water quality of the Yellow River is related to the healthy development of industry and agriculture in Ningxia. According to the Ningxia Water Resources Bulletin 2012-2017, we selected three representative water quality indicators of ammonia nitrogen (NH 3 -N), total phosphorus (TP) and permanganate index (COD Mn , and applied the single-factor and comprehensive water quality identification index method to evaluate the water quality of six national control sections in the Ningxia section of the Yellow River. The results showed that each section was most affected by NH 3 -N, followed by TP, and least affected by COD Mn ; The single-factor identification indexes of six sections were mostly falls into the category II, and the comprehensive identification indexes showed that the water quality mainly fell into the category II; Affected by the rapid development of the industry in this region, the water quality of the Mahuanggou section was seriously polluted.
