Claim 4:
5. A system for intelligent source tracing of organic pollution of a water body, which uses the method for intelligent source tracing of organic pollution of a water body described in of claim 4, the system comprising:
a data acquisition unit for acquiring organic matter analysis and detection data from a plurality of water samples of a polluted water body from upstream to downstream through high performance liquid chromatography-tandem mass spectrometry;
a pollutant determination unit for performing high-throughput screening on the organic matter in the water samples according to the analysis and detection data to determine pollutants in the water body;
a pollution source identification unit for identifying pollution sources by means of network analysis according to the determined pollutants; and
a pollution source evaluation unit for determining, according to the identified pollution sources and the organic pollutants in the receiving water body at the pollution sources, key pollutants in the pollution sources and quantifying the pollution contributions of the key pollutants by using a machine learning classification model.
