The invention relates to a single-pixel solar blind ultraviolet imaging system based on a space coding mask plate. A beam splitter prism is used for dividing optical signals collected by an imaging lens into solar blind ultraviolet signals and visible light signals; a solar-blind ultraviolet signal sequentially passes through the ultraviolet filter and the ultraviolet band imaging lens to filter out bands except solar-blind ultraviolet and then is imaged on the dynamic random coding mask device; the dynamic random coding mask device is used for spatial modulation of solar blind ultraviolet signals, and the modulated solar blind ultraviolet signals are collected to the ultraviolet band single-point detector through the ultraviolet band collection lens. A visible light signal sequentially passes through the visible light filter and the visible light band imaging lens and then is projected to the visible light band area array detector; the dynamic random coding mask device is used for continuously providing a pl
