摘　　要：根据治理与尺度对黄土区产流模式的影响 ,建立用地评价水土保持的措施减水效益的超蓄产流模型 ,并将径流成份直接区分为地表径流和地下径流。同时着重介绍所建模型参数的率定及其在减水效益中的应用。在3个典型流域 (青阳岔、岔巴沟和小理河 )的应用结果表明 ,该模型效果良好 。An infiltration-and-saturation-excess runoff model in evaluating the benefits of water and soil conservation has been established according to the control and scale influencing runoff-generation model in Loess region.This model could separate flow into two components,i.e.overland flow and flow under the ground.Calibration of model parameters and its application of calculating the benefits of water reduction in three small catchments (i.e.Qing Yingcha,Cha Bagou and Xiao Lihe)were introduced.The results showed that,this model was favorable and feasible.
