Identification of Slope Debris Flow Based on Fisher Discriminated Criterion

Abstract:

On the basis of analyzing formation condition of slope debris flow, optimize four indexes as the discriminated factors: the loose material reserves weighted by area (),effective particle size of the loose material ,geomorphic super entropy (),meteorological and hydrological index which is composed of indirect and direct antecedent precipitation and short duration rainfall (),use the basic data of slope debris flow in Beishan of Longnan City, build the Fisher discriminated analysis model , find out the discriminated function of debris flow and non-debris flow on slope is,critical value is 1.305,give the new method of identification on the slope debris flow.
