摘　　要：以铅山县桐木关流域内武夷山镇篁村作为评价对象,分析计算该流域设计暴雨、洪水;按实测河道断面资料,推求水位流量关系;结合现场入户调查、调研及历史山洪灾害调查情况,根据篁村所在流域控制断面地形地貌及两岸房屋分布情况确定成灾水位,以成灾水位对应洪峰流量的相应频率表示现状防洪能力,划定篁村居民住户危险等级和危险区的范围,并绘制危险区及转移路线图.Taking Huang village of Wuyishan town in Tongmuguan basin of Yanshan county as the evaluation object, based on the household investigation on the spot and the measured river cross-section data,the relationship between water level and discharge is ascertained.And combined with the investigation condition on the spot and mountain torrent disaster history and based on the control cross-section landform of Huang village and house distribution condition of two side of Tongmuguan River ,the disaster water level was determined.The corresponding frequency of the corresponding flood peak discharge on the disaster water level re-flects the flood control capacity. Finally, dangerous scope and dangerours grade of Huang village are determined. The dangerous area and the personnel transfer route map are drawn.
