Method for measuring and calculating soil carbon sink potential of water and soil conservation engineering measure

The invention discloses a method for measuring and calculating soil carbon sink potential of water and soil conservation engineering measures. The method comprises the following steps: firstly, dividing the water and soil conservation engineering measures into a point type and a surface type; for the point type engineering measure, the sediment retaining carbon sequestration amount of the point type engineering measure is finally calculated by measuring the maximum reservoir capacity and the layered sedimentation amount of the retained sediment amount, calculating the sediment retaining potential of the non-full-sediment part of the point type engineering and other parameters; and for the surface type engineering measure, calculating the carbon sequestration amount of the surface type engineering measure by calculating the service life of the engineering measure, measuring the area of a control region of the surface type engineering measure and calculating parameters such as soil erosion modulus with/without
