Abstract：Taking Tiexisectionof Weigong riverasthecore，the temporal changes，spatialgradientsand interaual evolutiontrendsof typicalsection waterqualityweresystematicallyanalyzed in2O24，andthe timeperiodsandcauses ofhigh-valuepollutionevents were identified.By investigating the types and distributionof discharge outlets，it was determinedthatthepollution load mainlycame from urbannon-point sources，pipeline overflowand tailwater input，and acomposite pollution sourceanalysis framework was constructed.On this basis，the dynamic high-frequency monitoring network and thresholdtriggredresponse mechanism were proposed toachieverapid identificationandaccurate tracing of polutionloads，and to improvethe scientificandforward-looking natureofurbanriverwaterenvironmental management.
