The invention discloses a saline and alkaline wetland damaged vegetation recovery method. The method comprises the following steps of determining the wetland damaged degree, and performing habitat investigation, wherein the salt content of the object wetland is detected, and the damaged degree of the wetland is determined according to the salt content and the PH value of soil, so that different recovery measures are adopted; performing habitat investigation, wherein the climate condition, the soil condition, water sources, vegetation and animal and plant resources of the object wetland are comprehensively investigated; the saline and alkaline wetland damaged vegetation recovery method comprises the steps of 1, stripping and removing saline-alkali soil on the existing surface layer of the object wetland; 2, soil organic matter is improved; 3, the organic matter soil is selected for covering the object wetland; 4, soil covers some stacked slopes to increase the ground, and the underground water level is increased; 5, a complete irrigation and drainage system is built, and the underground water level is controlled. The method is used for wetland soil salting prevention, the plant community is rebuilt, the plant survival rate and the vegetation coverage area are increased, the plant variety is enriched, and the maintenance cost is lowered.
