摘要：

黄土高原水土流失严重,以小流域土壤侵蚀最为活跃,是产沙最集中的地区。小流域不同地貌位置,侵蚀方式、能力和产沙量,均有明显的区别。掌握这个规律,采取有效的治理方法,就可获得较好的效果。戏河是关中盆地水土流失较严重的小流域,受骊山隆升影响,土壤侵蚀十分强烈,大量泥沙倾入水库,不仅库容逐渐变小,经济效益减少,还给下游人民生命财产造成威胁。要减少水库泥沙,就必须加强流域水土保持工作。

摘要：

The loess Plateau is characterized dy serious water and soil eresion. The most active soil erosion is in the small watershed in which sediment production is concentrated. There are the significant differences in erosion patterns, erodibility and sediment production in various landform locations in the small watersheds. The better results can only be obtained by having a good grasp of the rules and adopting effective controlling measures. The xihe watershed is a small watershed with serious water and soil erosion in Guanzhong basin. Affected by the rising of the Lishan Mountain, soil erosion here is so serious that the bulk of sediments are carried into the reserviors, which not only reduces the storage capacity and economic returns but also threatens the lives and properties of the people in the lower reaches. Therefore, it is necessary to strengthen work on soil and water conservation in the small watersheds in order to reduce sediment deposited in the reservoirs.
