| Abstract: | The high resolution satellite data of SPOT5 has better interpretation effect to the debris-flow hazards on the geological surveys of Dongchuan county. Based on the research of future of debris-flow in Dongchuan county,he interpretation indication of the debris flow was built up and the vale debris-flow and the sloping debris-flow were indentified. Totally 168 vale debris-flows and 95 sloping debris-flows were identified. |
