基于分布式水文模型SWAT模型，以大洋河沙里寨水文站以上为研究流域，利用沙里寨水文站2000-2010年水文数据、研究流域分辨率为1 Km ×1 Km土地利用数据以及1：100000土壤类型数据，定量模拟大城子以上流域2000-2010年径流量，通过设定三种土地利用模式情景，定量分析不同土地利用模式情景下对大洋河流域径流量的影响。研究结果表明：SWAT模型在大洋河流域径流模拟具有较好的适用性，模拟相对误差小于10％，确定性系数0.7以上；在三种土地利用模式情景，其中情景 II（林地减少10％，城镇用地增加10％）径流深增加7.7 mm，径流系数增加0.16，情景I（林地增加10％，旱地减少10％）以及情景 III（林地增加10％，城镇用地减少10％）使得径流深分别减少14.1 mm和16.2 mm，城镇用地对径流影响大于旱地。研究成果对于大洋河水资源规划和保护提供参考价值。

The article is based on the hydrological model SWAT model and study the effects of land used on the runoff in the Dayang river basin. To taKe Shalizhai hydrological stations hydrological data during 2000 -2010 years for the studied are-a,it researches the resolution of 1Km × 1Km land used data,and 1:100,000 soil types of data,the runoff during 2000 -2010 years in the Dayang river was simulated by year,by setting three land used scenarios,quantitatively analyzes the impact of different land used patterns on runoff scenarios. The results show that SWAT model is suitable for runoff simulation in the Dayang river,which simulation relative error is less than 10%,and the uncertainty factor more than 0. 7;scenario II(10%reduction in woodland,urban land increased by 10%)increase the runoff by 7. 7mm,and increased the runoff coefficient by 0. 16,the scenario I(10% woodland,upland reduced by 10%),and the scenario III(woodland increased by 10%,10%reduction in urban land)maKes runoff decreased by 14. 1 mm and 16. 2mm respectively,the impact of urban is greater than the dry land on the runoff. The achievement can provide a reference value to the protection of water resource in the Dayang River basin.
