摘要： Non-point source pollution of Ningxia Yellow River Irrigation has become increasingly prominent, making it an important factor affecting the water environment. Research on irrigation non-point source pollution and the progress of pollution control in irrigation has profound significance in terms of protecting the ecological security of irrigation. In the current paper, the Ningxia Yellow River irrigation area was used as the study area. The characteristics of the point source of its pollution are analyzed from literature. Through an analysis of relevant national laws and policies on environmental protection, as well as the policy of prevention and controlling non-point source pollution implemented by the Ningxia government, the non-point source pollution research progress on the Yellow River Irrigation area is summarized. The non-point source pollution in the Ningxia Yellow River Irrigation area is still acute. Crop pollution has been controlled, but the quantity of crop pollution is still serious. The animal manure pollution is growing every year. So, we still need to strengthen the non-point source pollution management.
