The invention discloses a forest carbon sink potential prediction method and device, and the method comprises the steps: inputting forest resource survey monitoring data or biomass survey data into a carbon reserve calculation model, and obtaining the carbon reserve of a forest patch; calculating the current carbon density of the forest plaque according to the area of the forest plaque and the carbon reserve of the forest plaque; determining the forest plaques with the same site condition and the same dominant tree species as the same type of forest plaques according to the site condition data and the forest survey data; sequencing the current carbon density of each forest plaque which is an over-mature forest in the same type of forest plaques to obtain a carbon sink saturation density value of the type of forest plaques; calculating the absolute value of the difference value between the current carbon density of each forest patch and the carbon sink saturation density value corresponding to the forest patch
