黄土高原坡沟系统土壤侵蚀研究进展
Research progress on soil erosion of slope-gully systems in the Loess Plateau
摘要
Abstract
The slope-gully system is the important units of watershed. It is not only the main source of erosion sediment yield from small watersheds, but also the basic treating units of controlling soil and water lose and restoring and reconstructing entironment in the Loess Plateau. Research of the erosion phenomenon and law of the system could provide important scientific foundation for optimal allocation of government measures on soil and water loss in the Loess Plateau. This study reviews the research progress about the erosion patterns of slope-gully system, the vertical zonality of erosion forms, the sources of sediments from the system, the influences of flows and sediments upstream on soil erosion of the system, the impacts of herbage vegetation coverage and its space distribution on the soil erosion of system, and the application of check dam to the system ' s soil erosion analysis etc. It points out that the vertical distribution of soil erosion and the effects of flows and sediments upstream on soil erosion of the system need further quantization. The sources of erosion sediment of the system, the impacts of check dam on soil erosion of system, and the herbage vegetation coverage of field slope-gully system and its influences of spatial distribution on soil erosion of the system also need to be strengthened.关键词
