Fractal Features and Scale Transformation of Watershed Sediment Transportation under LUCC
摘要
Abstract
Based on the information of soil erosion and sediment yield and transport extracted from watershed units of Luoyugou and Lv' ergou by WEPP model,the spatial variation law and impact factors of sediment transport rate and scale transformation of sediment transport were studied u-sing fractal theory.The results showed that the annual average sediment transport rate varied between 0.03 and 1.00 in various scales of watersheds,but it was stable for a given scale; the process of watershed sediment transport had fractal features, according to which a model of scale transformation for sediment transport rate was established integrating relative research results in other areas. Furthermore, an extensively applicable scale transformation model was given.关键词
