研究区受“5．12”汶川地震、“8．18”泥石流、“4．20”芦山地震等大型地质灾害叠加作用的影响，区域上构成独特的工程地质环境条件．通过系统调研和收集宝兴冷木沟地震前后泥石流物源地质原型和泥石流灾害防治的第一手资料，重点查清泥石流形成的物源条件，对比研究“4．20”芦山地震前后泥石流物源特征、动／静储量比例．分析研究结果表明冷木沟发育点状物源、线状物源、面状物源，其中震前震后均以沟床侵蚀物源（线状物源）为主，占76．110％和60．690％．“4．20”芦山地震后，沟岸堆积物源（点状物源）却成倍增多，为48的倍率，超31．490个百分点．整体上，除沟岸侧蚀物源（面状物源）外，同一流域段内，震后物源动储量高于震前．静动储量线性关系较为明显，相关系数R2达0．8～1．0，均属高度正相关．

“5.12”Wenchuan earthquake ,“8.18”debris flow,“4.20”Lushan earthquake and other large-scale geological disasters made additive effects on the study area,and constituted a unique engineering geological environmental condition.Through systematically investigate and collect geological prototype research of the debris flow material source before and after Lengmugou earthquake,Baoxing country and first -hand information of debris flow disaster prevention and control,the point research of the source condition of debris flow and comparative research before and after the "4.20"Lushan earthquake debris flow material source characteristics,dynamic and static material source reserve ratio,according to material source is one of the three conditions formed debris flow.The analysis results indicate that Lengmugou point material source,line material source and surface material source has well -developed,but the major is gully erosion source material (line material source),reaches 76.110% and 60.690% before and after earthquake.After Lushan earthquake, during the accumulation material source in shore ditch (point material source)increased exponentially,ratio of 48,by more than 31.490%.In addition to ditch shore erosion source material source (surface material source), dynamic reserves than before the earthquake source in the same watershed section.Static and dynamic material source reserves of linear relationship is relatively obvious,the correlation coefficient (R2 )of 0.8 ~1 .0,are positively related,and is highly relevant.
