摘要
沟槽是径流与输沙通道和侵蚀主体,沟槽侵蚀监测对揭示水土流失规律和进行流域产沙模拟有重要意义。在对黄土高原相关研究结果分析的基础上,对沟槽侵蚀进行了初步确定。同时对与沟槽侵蚀关系密切的泥沙输移比进行了分析,并总结出沟槽侵蚀与泥沙输移比监测和估算的沟道特征监测法、坡面产沙—出口站泥沙比较法、稀土元素示踪法、坝库泥沙还原法和经验公式拟合法等方法。
Groove is the channel of sediment delivery and the main body of soil erosion. Monitoring of groove erosion could not only help to know the soil erosion rules, but be very useful for the production of sediment at small watershed and regional scales. Based on some researches in the Loess Plateau, the groove erosion is described, and the meaning and usage of sediment delivery ratio are discussed. Several general monitoring and estimation methods of groove erosion and sediment delivery ratio are put forward.
