| 摘 要： | 应用土壤水体评价模型(SWAT)对苕溪流域径流量、泥沙、营养盐负荷进行模拟计算,分析了2008年苕溪流域非点源污染的时空分布特性.结果表明:苕溪流域非点源污染单位面积产生量表现为北部高于南部、东部高于西部、中部地区最少;耕地是泥沙和污染物产生的主要来源,其单位面积负荷远大于其他土地利用类型;产流量、产沙量与降水量呈显著正相关关系(P＜0.05),雨季(6-9月)的营养盐输出大于旱季(12月至次年3月);平均坡度与泥沙负荷、有机氮负荷及硝态氮负荷呈显著相关关系(P＜0.05). |

| Abstract: | By using soil and water assessment tool(SWAT) model,this paper simulated the surface runoff intensity and the export loadings of sediment particulates and nutrients via non-point source hydrological pathway in Tiaoxi watershed,and integrated with the simulation results,analyzed the temporal and spatial distribution characteristics of non-point source pollution in the watershed in 2008.In the study area,the per unit area non-point source pollution was stronger in northern region than in southern region and i... |
