摘要
豫西黄河流域是黄河泥沙的产区之一,严重的水土流失使黄河下游泥沙、洪水问题更加严峻。通过对研究区土壤侵蚀的地质环境及形态类型的调查研究,分析了研究区控制土壤侵蚀的主要地质环境特征,在此基础上依据不同地质环境特征,主要考虑地形地貌类型和地层岩性等地质环境条件的差异,将研究区土壤侵蚀环境类型划分为基岩山地丘陵侵蚀、黄土塬梁峁丘陵侵蚀、河谷侵蚀3种类型,这对于黄河的治理与开发以及区内生态建设具有重要的意义。
The west of Henan is one of the sediment producing regions of the Yellow River basin.The serious soil and water loss has made the issues of sediment and floods of the lower Yellow River even more severe.The paper analyzes the main characteristics of geologic environment for soil erosion control of the studied area through survey and study on geologic environment and morphologic types of soil erosion of the area.It mainly considers the differences of topography,geomorphology and lithology of stratum based on different characteristics of geologic environment and divides the category of erosion environment of the studied area into bedrock hilly area erosion,gullied rolling loess area erosion and valley erosion on the above basis.It has important meanings on further study of erosion mechanism of the region,management and development of the Yellow River and ecologic building of the region.
