Abstract黄土高塬沟壑区沟头溯源侵蚀非常普遍,已经对塬面地区的土地、农田、村庄民居、道路和工厂造成了严重的威胁。通过对董志塬的调查发现,影响溯源侵蚀的因素为自然和人为因素两类。自然因素主要包括降雨径流、地形地貌和土质。总结出溯源侵蚀的发生类型为水力冲刷型、陷穴诱发型、裂缝诱发型和人为诱发型。溯源侵蚀的过程从时间顺序上可分为3个阶段,主要分为水力冲刷阶段、水力和重力共同作用阶段、重力侵蚀阶段。最后,根据不同类型的沟头侵蚀与活动特点,提出了沟头的主要防护措施。
Other AbstractHead-cut is a widespread and serious erosion type on the Loess Plateau and it has already threatened farmlands, local residents, roads, and factories. According to the field investigation on Dongzhiyuan, the influence factors of head-cuts are natural and human factors. The natural factors mainly include runoff, topography, and soil. The genetic types of head-cut are summed up, including flow-induced type, sink hole-induced type, fissure-induced type, and human-induced type. According to the order of time, t...
