抽象的。本文重点特别是碎屑沉积物通量的堆积体斜坡。使用正射影像解释，实地测量和地理信息系统技术，量化的面积和体积的积极沉积物转移有关的特定地貌单位实现了不同的空间尺度。一个单一的地形复杂，更具体地说，一个岩屑片/岩屑锥复合体的更密切的调查，带来了光，再动员可以超过沉积物输入的一个因素的57。这可能是整个流域的预期情况的一个指标。目前。研究区约有9%的面积（3平方公里），包括堆石斜坡及谷底，主要透过重力及河流作用，进行沉积物迁移。来自这些活跃地区的最近的沉积物转移和整个山谷的体积（0.07公里3）的巨大的体积（117.174米3）的比较表明，但是，最大的一部分必须与再活化沉积物，不能被认为是从相邻的岩壁沉积物输入。这一结论也得到了泥沙输入的直接测量的支持。
Abstract. This paper focuses in particular on clastic sediment fluxes on talus slopes. Using orthophoto interpretation, field measurements and GIS-techniques, a quantification of areas and volumes of active sediment transfer related to specific landform units was achieved for different spatial scales. Closer investigation of a single landform complex, more specifically a talus sheet/ debris cone-complex, brought to light that remobilisation can overbalance sediment input by a factor of 57. This could be an indication of what may be expected in the whole catchment. At present. approximately 9% of the research area (3 km 2 ), comprising talus slopes and valley bottom, is characterised by sediment transfer mainly through gravilational and fluvial processes. A comparison of the vast volumes (117.174 m 3 ) derived from these active areas of recent sediment transfer and the volume of the entire valley fill (0.07 km 3 ) indicates, however, that the largest part must be related to remobilised sediments and cannot be considered as sediment input from the adjacent rockwalls. This conclusion is also supported by direct measurements of sediment input.
