            Abstract In  order  to  better  understand  the  characteristics  and  sources  of  pollutants  in  Daliao  River  Basin,  the
            spatial  topological  relationship  of  "Watershed-Control  unit-Administrative  district"  was  established,  the  water
            quality of the state-controlled sections of Daliao River Basin, the amount of pollutants into the river in every control
            unit, and the spatial distribution characteristics in 2019 were analyzed. The results indicated that: 1) Among 28 water
            quality monitoring sections in Daliao River Basin, 29% of the monthly water quality could reach the targets of the
            Action Plan for Prevention and Control of Water Pollution. COD and NH -N were the main pollutants that exceeded
                                                                         3
            the standard. In the section exceeding the standard, the main sources of COD and NH -N were urban life sources,
                                                                                     3
            rural life sources and decentralized livestock and poultry breeding, while TP mainly came from pollution sources of
            different land use types and urban life sources. 2) The amount of COD, NH -N, TN, and TP pollutants into the river
                                                                           3
            was 59 195.5, 3 115.5, 18 229.7, and 538.3 t/a, respectively. The contribution rate in descending order was urban
            living source, rural living source, decentralized livestock and poultry breeding source, source of various landuse
            types  (including  woodland,  grassland,  farmland,  urban  land),  industrial  source,  large-scale  livestock  and  poultry
            breeding source. 3) The spatial distribution of the inflowing amount of pollutants into the river in descending order
