Ascertaining the relationship between “source-sink” landscape and non-point source (NPS) pollution is crucial for reducing NPS pollution, however, it is not easy to realize this target on cell unit scale. To reveal the relationships between “source-sink” landscape and NPS pollution based on cell uni...
