Following quite a while of treatment, the water contamination circumstance in the Huaihe Stream Bowl (HRB) is as yet horrid and rural nonpoint source contamination has turned into the main source of the issue. Be that as it may, rural nonpoint source contamination in the HRB is convoluted because of the intensifying impacts of different variables. In this review, we originally applied the product coefficient model to appraise the all-out nitrogen (TN) and all out phosphorus (TP) loads utilized as two contaminations source markers in HRB. Then, at that point, we built a record assessment arrangement of nonpoint source contamination risk by coupling the two source markers with five extra markers: precipitation disintegration, stream network dispersion, soil erodibility, incline length and land use. The essential wellspring of TN and TP loads is compost application, trailed by animals and poultry reproducing and rustic home-grown squanders. The gamble appraisal results show that 66.43% of the HRB is at medium to high take a chance of nonpoint source contamination, 12.37% is at high gamble and 11.20%. In addition, the medium-to-highrisk regions are predominantly packed in the Henan and Anhui territories. Conversely, the medium-risk districts are for the most part conveyed along the standard of the Huaihe Waterway. At long last, the noticed water quality classifications were utilized to check our discoveries. The controlling areas of nonpoint source contamination in HRB are recognized. This study could give a logical premise to successfully forestalling and treating water contamination in the HRB.
