Other AbstractThe managements of torrents and debris flow hazards were conducted by two divided ministry in China(i. e. the Ministry of Water Resources and the Ministry of Land and Resources). The properties of disaster determine which ministry should take the responsibility for disaster reduction and prevention strategies. In order to realize the scientific prevention and controls of torrents and debris flow,it is urgent to establish a unified regulation of hazards identification which based on the properties. In this paper,we analyzed the movement characteristics, types and development tendency of mountain torrent and debris flow,and established the rules for identification of properties which associated with disasters and watersheds. The differences between torrent disasters and debris flow disasters were analyzed from the characteristics of formation,movement,disaster body and accumulation. And we determine the properties of disasters based on the fluid properties of disaster body location,the proportion of casualty and economic losses that caused by mountain torrents and debris flow. Given that there is the possibility of mutual transformation between torrents and debris flow under different geological environment,this paper introduced the concept of time to discuss the discrimination of the flood and debris flow from the past and future. To be convenient for application,we takes the Hongba River in Shimian County and Aizi gully in Ningnan County as example to further illustrate how to discriminate the torrents and debris flow gullies and disasters.
