中文摘要	震后北川县泥石流灾害具有暴发频率高,规模大,潜在危害严重等特点,已经成为灾后恢复重建的关键制约因素。震后潜在泥石流发育度的评价,对灾后重建具有重要意义。在野外调查和遥感解译的基础上,利用Arc-GIS技术,采用多因子叠加法对震后北川县潜在泥石流发育度进行了评价。依据评价结果,把北川县分为泥石流高发育区、中等发育区和低发育区。高发育区集中于擂鼓镇—曲山镇—陈家坝乡一带,沿发震断裂上盘分布,占县域面积的6.6%;中等发育区位于高发育区两侧,以断裂上盘为主,占县域面积的22.5%;其余属低发育区,占县域面积的70.9%。在泥石流高发育区必须规避泥石流灾害;在中等发育区,应进行泥石流危险性评估,确保没有灾害威胁,否则也必须进行规避。
英文摘要	The debris flow hazards followed the Wenchuan earthquake have been the key restricting factor to the restoration and reconstruction in Beichuan County.The developing degrees evaluation of debris flow is of great significance to the reconstruction.Using ArcGIS technology and multi-factor superposition method,the developing degrees of debris flows in Beichuan County followed the Earthquake was evaluated based on the field survey and remote sensing interpretation.Landslides density,formation lithology,seismic intensity,slope gradient,surface roughness,and average annual precipitation were selected as evaluation factors and each of them was subdivided into five grades.Analytic Hierarchy Process(AHP) was used to determine the weights of factors and quantify each grade.On that basis,multi-factor weighted superposition evaluation model was constructed and used to evaluate the developing degrees of debris flow in the study area.According to the evaluation results,the study area was divided into three areas:high growth area,medium growth area and low growth area.The high growth area concentrated on the hanging wall of Beichuan-Yingxiu Fault and distributed along Leigu-Qushan-Chenjiaba townships,accounting for 6.6% of the study area.The medium growth area located on both sides of the high growth area and mainly on the hanging wall of Beichuan-Yingxiu Fault,accounting for 22.5% of the study area.The rest belonged to low growth area,accounting for 70.9% of the study area.It was suggested that human activities should avoid debris flows in the high growth area and debris flow disaster evaluation should be conducted in the medium growth area to ensure no disaster threat,or must avoid debris flow,too.
