The invention belongs to the technical field of underwater imaging, and relates to a single-photon imaging simulation method based on ocean turbulence. The problem that the accuracy is low due to the fact that an existing imaging simulation method does not consider the influence of turbulence on laser transmission in water is solved. The method comprises the following steps: firstly, determining an ocean turbulence model, then simulating the influence of ocean turbulence on the transmission of light beams in water, then determining the simulation reflectivity and simulation depth of each pixel after a target image passes through the turbulence model, and further calculating the simulation reflectivity of the target image after passing through a single-photon imaging system based on ocean turbulence; and finally, based on the simulation reflectivity and the simulation depth, describing a photon counting process by using Poisson response to complete simulation. According to the method, the influence of attenuat
