摘要
河北省太行山区是河北省泥石流灾害的主要发生区,该区泥石流在空间上主要分布在太行山东麓的中低山区域,其分布与暴雨等值线的中心部位基本吻合;在时间分布上主要发生在每年7月20日至8月10日之间的强暴雨时期。泥石流的暴发受到降雨因素和地质因素的双重影响,由于降雨为第一主控因子,在地质地貌条件充许的前提下,决定着泥石流是否能在暴雨中被激发。
The debris flow is main geological disasters in Taihang Mountains.It is mainly distributed in the Low region in Taihang Mountains and outbreaks between the torrential rain period in every year from July 20 to August 10,The outbreak of debris flow by rainfall factors and the dual effects of geological factors.Due to rainfall for the first dominative factor,determines the debris flow in storm whether can be inspired.The paper makes a research and analysis on the precipitation factors.
