【摘要】 汶川8.0级特大地震引发的大量山地灾害造成了严重水土流失,属于暴发性水土流失范畴。准确把握暴发性水土流失的成灾特征是生态重建的前提。结合汶川地震灾害调查和资料调研,揭示出汶川地震灾区暴发性水土流失的类型、强度、规模、分布以及后期演化等成灾特征,有针对性地提出防治的生态重建、灾害监测治理过程中的几个关键问题,体现了灾害与环境认识统一、灾害治理与生态保护相关联的理念。更多还原

【Abstract】 A large number of mountain hazards which are triggered by M8.0 Wenchuan earthquake have caused serious soil erosion,and the mountain hazards is the scope of fulminant soil erosion. Since it is the premise of ecological restoration to accurately grasp the characteristics of fulminant soil erosion,it reveals the disaster characteristics for the types,strength,size,distribution and the late evolution of fulminant soil erosion in Wenchuan earthquake stricken area,and proposes several key issues targeted the ecological reconstruction and the treatment of the soil erosion,which is the concept that disasters and environment are in unity,moreover,the disaster management is associated with the ecological protection.更多还原
