陕西省黄土高原塬面保护措施探索与研究
|
摘要
通过分析陕西黄土高原塬面侵蚀特性,探索塬面保护各项措施布设,为优化治理措施设计提供借鉴。根据陕西黄土高原塬面区水土流失特点,统计调查近期实施的塬面保护项目,分析各项措施的建设难易、成本高低、效果好坏,总结不同措施建设经验,提出塬面保护优选方案。在塬面保护措施中,为解决塬面集中排水冲刷而采取排洪沟、排水竖井、涝池调蓄、沟边埂等多种工程措施,可起到较好效果。
In order to optimize design of erosion control, protection measures for plateau surface are worked out in accordance with the features of soil erosion on the surface of Loess Plateau in Shaanxi Province. Options of plateau protection are proposed with consideration of main characters of soil and water losses, and based on statistics of recent implemented protection projects as well as comparison of costs, intensity of construction and benefits. Among protection options, structural measures that used to prevent large discharge and scouring from the surface, such as flood drainage ditch, shaft, pond regulation and ditch along the gully edge, can play big roles and are more effective.
