本文在野外调研和室内资料查阅的基础上．讨论了滑坡完全堵江的主要模式及其发生的地形、地貌条件和河床水动力条件．为滑坡堵江的预测提供了依据。 This article is based on field research and indoor data access. The main modes of landslide complete blocking of the river and its topography, geomorphic conditions and riverbed hydrodynamic conditions are discussed. It provides the basis for the prediction of landslide plugging.
