黄土高塬沟壑区产沙驱动力及减沙潜力分析
Driving Force of Sediment Production and Potential of Sediment Reduction in the Gullied Rolling Loess Area
摘要
Abstract
The sediment reduction trend in the core gully plateau region of Loess Plateau which located in the Jinghe River is still inconspicuous, while the sediment yield of most tributaries in the upper and middle reaches of the Yellow River reduced significantly since 1970s. This phenome-non is related to the special sediment production mechanism of the gullied rolling loess area. This study shows that:the runoff intensively run along tableland to valley is the major driving force for sediment production,especially the runoff running along the courtyard and road in the tableland to valley;the potential sediment reduction of terraces,tree and grass vegetation are hardly over 10% in the regions that tableland area accounted for more than 60% of the whole plateau region;reducing the runoff running along tableland to valley as much as possible is the key factor to control e-rosion and sediment yield.关键词
