| Abstract: | Mt. Gongga is called tourist paradise for its plateau, canyon, snow peak and glacier, hot spring, lake, forest, and Tibetan and Yi Minority culture. Influenced by the factors of special geographic location, geomorphology, geology and geo-tectonics, hydrology, and weather, all types of debris flow hazards frequently break out and greatly endanger scenic resources, basic facilities, tourist safety, and surrounding environment of the scenic spots in Mt. Gongga. Finally, mitigation countermeasures such as particular investigation and risk evaluation, fatalness analysis, scenic spot disaster mitigation planning, establishment of a hazard prediction and warning system, construction of warning signs for tourists, systematical debris flow control, and zoological protection are put forward. |
| Keywords: | Mt Gongga scenic spot debris flow hazard mitigation countermeasure |
