Abstract：Based on multiple factors including population and industry,pollutant discharge into rivers,river water quality,and pollutant flux,and combined with current pollution source surveys,this study identifies key targets for watershed water environment management in agricultural and rural areas by pinpointing major pollution sources and analyzing pollutant fluxes in river systems,using the Yanzhou River in Hainan Province as a case study.Data analysis indicates that livestock and poultry farming,as well as aquaculture,are the primary pollution industries within the Yanzhou River basin.The Nanyang River,Chentukeng Watercourse,Xiwei Watercourse,and Malan Watercourse are identified as key tributaries requiring focused management.This identification provides direction and targets for water environment management aimed at achieving compliance at water quality monitoring sections,effectively addressing challenges such as the broad scope of management,diverse pollution sources,and high governance difficulty in agricultural and rural areas.Corresponding management strategies are proposed:during water pollution control efforts,priority should be given to managing pollution from livestock and aquaculture along tributaries with high pollutant flux and inferior Class V water quality,while simultaneously addressing deficiencies in urban sewage treatment facilities to promote compliance at water quality monitoring sections.This research aims to provide a reference for implementing watershed water environment management in agricultural and rural areas under the rural revitalization strategy.
