摘要： China has been confronted with severe agricultural nonpoint source pollution (AGNSP) from livestock and poultry, which increases chemical oxygen demand (COD). To explore the sources of COD in surface waters from the perspective of ecosystem processes, taking the coastal watershed of the Yellow River Delta (YRD) of China as a typical study area, we have adopted a method that integrates the scale and positioning of livestock and poultry breeding, a pollutant generation coefficient, and kernel density estimation (KDE) to assess the COD diffusion risk during watershed soil erosion processes. Moreover, verification and analysis were performed by combining soil sampling data with hydrological and water quality monitoring data for the estuary. Additionally, we selected Spearman's coefficient for correlation analysis between surface soil organic matter (SOM) and related natural-anthropogenic factors. The main conclusions are as follows: the terrestrial COD pollution risks generated by livestock and poultry significantly influence SOM (p < 0.001) and are most strongly correlated in non-arable lands, especially saline-alkali land (rs = 0.86) mainly because of natural soil erosion process. Arable land has the highest SOM concentrations but has lower correlations with the COD generation risks obtained by the KDE method, mainly because of cultivation activities. At the watershed scale, surface runoff is the dominant driver of estuarine COD fluxes but has certain dilution effects on COD concentrations. Furthermore, there usually exists the spillover effects of AGNSP from livestock and poultry usually occur due to the imbalanced distributions between the area of arable land and the supply of manure within watersheds. Our study provides an effective and rapid assessment method for determining the AGNSP risk of COD derived from livestock and poultry.
