北京山区为泥石流多发区 ,共有泥石流沟 50 0多条 ,其中不乏河谷型泥石流。为了对北京山区河谷型泥石流进行深入研究和合理防治 ,选择一条无论地质历史时期还是近代 ,泥石流活动都十分活跃的柯太沟作为研究对象 ,以期通过对该沟泥石流的危害、形成条件和发展趋势的研究 ,提高对北京山区河谷型泥石流的认识和了解 ,从而提出更为合理的减灾对策和防治措施。
There are more than 50 mud-rock ditches in Beijing’s mountainous area, where there are many mud-rock flow areas. In order to conduct an in-depth study and reasonable prevention and control of the valley-type debris flow in mountainous areas of Beijing, a study of the Ke-ditch, which is active both in the geological history and in the modern times, was selected as the research object in order to establish the conditions and development trend through the hazard to the debris flow in the valley Research to raise awareness and understanding of the valley-type debris flow in mountainous areas in Beijing so as to propose more reasonable mitigation measures and prevention and control measures.
