Formation Characteristic and Comprehensive Classification of Debris Flow in Typical Mountain Area of the North of China
Debris flow is one of the familiar natural disaster in mountain areas, and is a kind of speacial flood current with great destructive power.The formation characteristics and classification of debris flow are the foundation of mechanism analysis, predication and forecast, disaster prevention and reduction.In this research, a typical mountain area of the north of China is selected as the study area.Meanwhile, based on analyzing the formation characterisitics of debris flow hazards, the comprehensive classification of debris flow is carried out according to the the five aspects, such as water source, landform features, material composition, damage degree, and human activity.In the study area, the formation of debris flow is mainly controlled by the factors of geology and rainfall, and the rainstorm-inducing feature is very obvious.Most of the debris flow in the study area should belong to rainstorm-gully-water-rock flow type.
