Abstract
The Total-Phosphor(TP) level and the phosphorus pollution status of Three-gorges Reservoir in recent years were analyzed,and the results showed that TP became one of the restrict factors affecting the water quality of Three-gorges Reservoir,and the pollution of the branches was more serious than that of the main flowing.Furthermore,the sources of phosphor of Three-gorges Reservoir were analyzed,and the results indicated that most of phosphor came from the inflow of upper reach,and next the non-point sources around the region of Three-gorges Reservoir.And finally,based the sources of phosphor of Three-gorges Reservoir,some countermeasures were put forward.
