摘　　要：基于SWAT模型建立了汶水河流域非点源污染模型,估算了流域内污染物负荷,利用经验公式预测了径流通过滨水缓冲带边界时的污染物浓度,通过相关性分析识别了决定该河段滨水缓冲带最小安全宽度的关键变量。结果表明:1)SWAT模型适合进行径流、总氮(TN)和总磷(TP)模拟。2)地表径流中TN和TP负荷由上游至下游呈增加趋势。3)滨水缓冲带安全宽度受到连接度、坡度、耕地面积和人口密度的影响。上、中、下游滨水缓冲带应各自维持77.90、33.37、60.65 m的安全宽度。A non-point source pollution model for the Wenshui River Basin was established based on the SWAT model.The nutrient load in the basin was estimated.The concentration of pollutants when runoff passed through the boundary of the riparian buffer zone was predicted using empirical formulas.The key variables determining the minimum safe width of the riparian buffer zone in this river section were identified through correlation analysis.The results showed that:1)The SWAT model was suitable for simulating runoff,total nitrogen(TN)and total phosphorus(TP).2)The TN and TP loads showed an increasing trend from upstream to downstream.3)The safe width of waterfront buffer zones was affected by connectivity,slope,cultivated land area,and population density.The upstream,midstream,and downstream waterfront buffer zones should maintain safe widths of 77.90,33.37 and 60.65 meters respectively.
