The invention discloses a mountain flood disaster forming time determination method, belongs to the technical field of mountain flood disaster early warning, and aims to provide the mountain flood disaster forming time determination method which solves the problem in reasonable determination of maximum rainfall in a period corresponding to disaster forming flood during operations of determining an early warning index by utilizing a statistical method and performing testing and rechecking on the early warning index. According to the method, an average value of a disaster forming time initial value and disaster forming flow occurrence time is taken as disaster forming time, wherein the disaster forming time initial value t(initial) is determined according to a critical curve of rainstorm and an ''accumulated individual rainfall-first 1h rainfall-time'' curve; the disaster forming time initial value t(initial) refers to time corresponding to a first intersection point of the two curves; and the disaster forming
