Abstract: Taking Huangshan scenic area as the research area, this study discusses the applicability of risk zonation of mountain torrent disasters in relatively closed regions. Based on natural disaster risk assessment theory and mountain torrent risk formation mechanism, the risk zoning of mountain torrent disaster was formed for Huangshan scenic area by using meteorological data, integrating factors of nature, social economy, geographic information data as well as mountain torrent-caused disaster. Results indicate that the high-risk areas are mainly distributed in the northeast and southwest of scenic region, including Ciguangge, Wenquan, Yungusi, Paiyunlou, northern of Beihai, Tianhai, etc., which are dense region of tourist and essence of scenic spots. While the low risk areas are mainly distributed in the northeast and southwest of scenic region, including Fugu, Yanghu, and Fuxi, etc. Tangkou town is the base of life and tourist reception, which is located in medium to high risk area. Because of population and buildings being highly concentrated, the mountain torrents disaster of Tangkou should be highly vigilant. The result of regionalizing risks is consistent with the actual situation according to historically typical rainstorm torrent disasters. The paper introduces the technology and method of regional risk zonation of mountain torrent disasters in Huangshan scenic area, which could provide scientific basis and reference for prevention of weather disasters in mountain tourism scenic spot.
