Study on Agricultural Non-Point Source Pollution Based on SWAT
Nonpoint source pollution, especially agriculture nonpoint source pollution is the major reason resulting in eutrophication in many receiving water bodies. At first, agriculture nonpoint source pollution and the harm pollutants bring is analyzed. Then around the questions about how the nonpoint source pollutants export from the soil and how much pollutant import into the receiving water, my study provide an overview of the progress of research on pollution forming mechanism, pollutants leaching from soil and pollutants migrating with streamflow into water body, and briefly summarizes the history of nonpoint source load estimation include model developing and application, and introduce the SWAT model which will be applied in my study. At last, I look forward to some important research direction in pollution mechanism and load estimation.
