摘　　要：实践证明 ,黄土高原地区以骨干坝、淤地坝为主的沟道工程、小流域坝系 ,在拦泥淤地、防洪保收、水资源利用、灌溉、养殖、人畜饮水、改善交通等方面发挥了重要作用 ,成为不可缺少的水土保持重要措施。沟道工程的防洪实践证明 ,只要形成以治沟骨干工程为骨架 ,以小多成群的淤地坝为主体的沟道坝系 ,完全可以保证沟道工程的安全。Practice proved that the channel project and the dam system in small watershed with key dams and warping dams in the Loess Plateau played important roles in sediment retention and farmland-making, flood control,use of water resources, irrigation, fishery, drinking water supply and improving traffic condition. It is becoming the most important measure in soil and water conservation. The flood control activity in gully area proved that engineering works in gullies be safe where there is a solid frame with key dams and amount of warping dams in a small watershed.
