An approach to mass movements in the Jiuzhaigou catchment

ABSTRACT

This paper presents a preliminary study of the main types, featurres, genesis and counterrmeasures of mass movements in the Jiuzhaigou catchment, which is one of the most scenic region in China. The main features are debris flows, rock-segment flows, landslides, and avalanches. Rough relief, fractured rocks, drifts, steep slopes, intensive rainstorms, and earthquakes produced their geneses. Countermeasures should include the integration of engineering and biological projects (AU)
