摘要
石棉—冕宁地区新第三纪以来的新构造活动强烈，主要表现为断裂构造、线性地貌及河流阶地发育地震、滑坡及泥石流活动频繁，分布广泛。新构造运动具有普遍性、继承性、方向性及阶段性等特点。研究区可划分出５个未来可能发生强震的潜在震源区、３个滑坡及７个泥石流极度危险区。建议对这些地质灾害采取躲避、预测预报和综合治理。
Strong neotectonism in Shimian Mianning region finds expression in development of faulted structure,linear landform and river terrace and frequent earthquake,landslide and mud rock flow It is characterized by widespread scope,inheritance,orientation and in stage The studied region may be divided into 5 possible pleistoseismic zones,extremely dangerous 3 landslide areas and 7 rock mud flow areas Take preventive and control measures to these geological hazards
