Ashi River Basin was selected as the study area to establish soil and water assessment tool (SWAT) model under the support of the scenario simulation technology to simulate the returning farmland to forest, terracing, fertilizer reduction,vegetation filtering belt strips,their syntaxic control measures and its comprehensive effect.Results showed that:returning farmland to forest mode could reduce 1.03%~5.35% of NPS-TN load and 0.94%~8.09% of NPS-TP load. Terracing mode could reduce 0.51%~2.77% of NPS-TN load and 0.49%~4.54% of NPS-TP load. Fertilizer reducing mode could reduce 0.65%~6.52% of NPS-TN load and 0.01%~2.95% of NPS-TP load. Filter strips mode could reduce 42.62%~69.51% of NPS-TN load and 80.09%~86.27% of NPS-TP load. Syntaxic mode could reduce 34.90%~54.36% of TN load and 35.32%~60.89% of TP load. For reaching the water quality goal of 'Environmental quality standards for surface water' (GB3838-2002), 45.87%~82.53% of PS-TN load and 35.58%~66.85% PS-TP load should be reduced yet.
