Abstract： At present，therearecore problems inthe treatment of river discharge outlets，such as incomplete inspection， inaccurate measurementandunclear tracing.Taking thesmallwatershedin themiddlereachesof theHuaiheRiver（covering an area of 3200km2 ）as the research area，a full chain technical system of“investigation—monitoring—traceability” isconstructed.Through amultidimensional investigation system （integrating sateliteremote sensing，unmannedaerial vehicles，ground verification，and underwaterreconnaissance），the comprehensive identification of concealed sewage outlets is achieved， with an eficiency improvement of 6 00% compared to manual inspections.By real-time monitoring of thenetwork （point linesurface combination），high-frequency monitoringand dynamicresponseareachieved，andhe data efficiency is improved to 98.2% . By coupling traceability models （integrating water quality， water quantity， isotopes， and machine learning）， the traceability accuracy is improved to 93.8% ，with a positioning deviation of no more than 50m Practical application has shown that this system significantly improves the compliance rate of sewage outlets and water environment quality，thus providing effective technical support for precise watershed management.
