Abstract：To grasp thecurrent situationof watershed non-point source polution inreservoir-type water sources in hily areas，and explore theriskofregional pollutant discharge and countermeasures forpreventionandcontrol，QiaodianReservoir n Jinan Citywas taken asthe studyarea，andtheoutputcoeficient method combined with theequivalent polution loadintensitywas used to estimateand analyze the agricultural non-point source pollution discharge，discharge intensity anddistributioncharacteristicsofthestudyarea in2O22，andclassfytherisk levelof pollution discharge.Theresults showthattheemissionintensityofagricultural non-point sourcepolutioninthe studyareaasa wholeisonthelow side， andthe highly poluted areas are mainly located in the upper reaches of the basin.The main sources of pollution in the study areaare livestock and poultry breeding sources，and the polution emissions from domestic sources and planting sourcesare relativelysmall，the dominant areas ofbreeding sources account forahigh percentage andare mostlydistributed in theupperreachesof the basin.The polution risk inthestudyareashows atrendof increasing from the downstream （the southwestern region） to the upper reaches （the northeastern region）.
