水土流失治理背景下小流域泥沙来源初探——以皇甫川流域西五色浪沟小流域为例
Preliminary study on sediment sources of watershed under control of water loss and soil erosion:Taking Xiwuselanggou Watershed of Huangfuchuan Basin as the example
摘要
Abstract
Based on the high-resolution images obtained from remote sensing, this study were conducted in Xiwuselanggou Watershed of Huangfuchuan Basin. CIS technology was applied to determine the upper edge line of the watershed. The watershed was divided into two relief types, I. E. The gully area and the inter-rill land. Sediment sources of the watershed, where control of water and soil loss is ongoing, were compared by two aspects. The first aspect was according to the amount and distribution of local gully erosion and surface erosion, and their influential factors including cutting intensity, as well as water and soil conservation measures and land use mode, gradient, and vegetation coverage, etc. ; the second aspect was based on the observation data of the rainfall stations, port stations, and runoff plots distribution in the watershed. Both the two aspects showed that local sediment was mainly produced from the gully area, and soil erosion amount of the gully area was 2. 73 times as much as that of the inter-rill land, making up about 73% of the total erosion amount in the watershed.关键词
